Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642524, here are decompositions:

  • 5 + 8642519 = 8642524
  • 17 + 8642507 = 8642524
  • 71 + 8642453 = 8642524
  • 383 + 8642141 = 8642524
  • 461 + 8642063 = 8642524
  • 467 + 8642057 = 8642524
  • 491 + 8642033 = 8642524
  • 521 + 8642003 = 8642524

Showing the first eight; more decompositions exist.
