Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987400, here are decompositions:

  • 7 + 4294987393 = 4294987400
  • 13 + 4294987387 = 4294987400
  • 43 + 4294987357 = 4294987400
  • 97 + 4294987303 = 4294987400
  • 349 + 4294987051 = 4294987400
  • 409 + 4294986991 = 4294987400
  • 433 + 4294986967 = 4294987400
  • 607 + 4294986793 = 4294987400

Showing the first eight; more decompositions exist.
