Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477598, here are decompositions:

37 + 31477561 = 31477598
151 + 31477447 = 31477598
199 + 31477399 = 31477598
277 + 31477321 = 31477598
307 + 31477291 = 31477598
457 + 31477141 = 31477598
487 + 31477111 = 31477598
499 + 31477099 = 31477598

Showing the first eight; more decompositions exist.
