Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61438, here are decompositions:

  • 29 + 61409 = 61438
  • 59 + 61379 = 61438
  • 107 + 61331 = 61438
  • 227 + 61211 = 61438
  • 269 + 61169 = 61438
  • 317 + 61121 = 61438
  • 347 + 61091 = 61438
  • 431 + 61007 = 61438

Showing the first eight; more decompositions exist.
