Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749492, here are decompositions:

  • 23 + 8749469 = 8749492
  • 41 + 8749451 = 8749492
  • 53 + 8749439 = 8749492
  • 71 + 8749421 = 8749492
  • 149 + 8749343 = 8749492
  • 263 + 8749229 = 8749492
  • 293 + 8749199 = 8749492
  • 359 + 8749133 = 8749492

Showing the first eight; more decompositions exist.
