Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739580, here are decompositions:

  • 89 + 8739491 = 8739580
  • 149 + 8739431 = 8739580
  • 191 + 8739389 = 8739580
  • 281 + 8739299 = 8739580
  • 383 + 8739197 = 8739580
  • 461 + 8739119 = 8739580
  • 467 + 8739113 = 8739580
  • 557 + 8739023 = 8739580

Showing the first eight; more decompositions exist.
