Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294986390, here are decompositions:

  • 17 + 4294986373 = 4294986390
  • 47 + 4294986343 = 4294986390
  • 59 + 4294986331 = 4294986390
  • 113 + 4294986277 = 4294986390
  • 139 + 4294986251 = 4294986390
  • 179 + 4294986211 = 4294986390
  • 181 + 4294986209 = 4294986390
  • 193 + 4294986197 = 4294986390

Showing the first eight; more decompositions exist.
