Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499954, here are decompositions:

61 + 31499893 = 31499954
151 + 31499803 = 31499954
193 + 31499761 = 31499954
223 + 31499731 = 31499954
457 + 31499497 = 31499954
463 + 31499491 = 31499954
487 + 31499467 = 31499954
523 + 31499431 = 31499954

Showing the first eight; more decompositions exist.
