Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690042, here are decompositions:

  • 61 + 8689981 = 8690042
  • 73 + 8689969 = 8690042
  • 199 + 8689843 = 8690042
  • 313 + 8689729 = 8690042
  • 331 + 8689711 = 8690042
  • 433 + 8689609 = 8690042
  • 499 + 8689543 = 8690042
  • 643 + 8689399 = 8690042

Showing the first eight; more decompositions exist.
