Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987278, here are decompositions:

  • 47 + 4294987231 = 4294987278
  • 137 + 4294987141 = 4294987278
  • 167 + 4294987111 = 4294987278
  • 227 + 4294987051 = 4294987278
  • 311 + 4294986967 = 4294987278
  • 367 + 4294986911 = 4294987278
  • 389 + 4294986889 = 4294987278
  • 521 + 4294986757 = 4294987278

Showing the first eight; more decompositions exist.
