Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747390, here are decompositions:

  • 61 + 8747329 = 8747390
  • 139 + 8747251 = 8747390
  • 199 + 8747191 = 8747390
  • 271 + 8747119 = 8747390
  • 307 + 8747083 = 8747390
  • 349 + 8747041 = 8747390
  • 433 + 8746957 = 8747390
  • 541 + 8746849 = 8747390

Showing the first eight; more decompositions exist.
