Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747722, here are decompositions:

  • 149 + 8747573 = 8747722
  • 233 + 8747489 = 8747722
  • 239 + 8747483 = 8747722
  • 251 + 8747471 = 8747722
  • 281 + 8747441 = 8747722
  • 449 + 8747273 = 8747722
  • 461 + 8747261 = 8747722
  • 479 + 8747243 = 8747722

Showing the first eight; more decompositions exist.
