Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542890, here are decompositions:

  • 17 + 542873 = 542890
  • 53 + 542837 = 542890
  • 59 + 542831 = 542890
  • 107 + 542783 = 542890
  • 167 + 542723 = 542890
  • 197 + 542693 = 542890
  • 311 + 542579 = 542890
  • 353 + 542537 = 542890

Showing the first eight; more decompositions exist.
