Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749430, here are decompositions:

  • 7 + 8749423 = 8749430
  • 13 + 8749417 = 8749430
  • 73 + 8749357 = 8749430
  • 211 + 8749219 = 8749430
  • 223 + 8749207 = 8749430
  • 439 + 8748991 = 8749430
  • 457 + 8748973 = 8749430
  • 541 + 8748889 = 8749430

Showing the first eight; more decompositions exist.
