Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502642, here are decompositions:

  • 11 + 502631 = 502642
  • 29 + 502613 = 502642
  • 89 + 502553 = 502642
  • 191 + 502451 = 502642
  • 233 + 502409 = 502642
  • 383 + 502259 = 502642
  • 461 + 502181 = 502642
  • 509 + 502133 = 502642

Showing the first eight; more decompositions exist.
