Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998402, here are decompositions:

  • 3 + 998399 = 998402
  • 73 + 998329 = 998402
  • 241 + 998161 = 998402
  • 331 + 998071 = 998402
  • 373 + 998029 = 998402
  • 439 + 997963 = 998402
  • 523 + 997879 = 998402
  • 619 + 997783 = 998402

Showing the first eight; more decompositions exist.
