Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514502, here are decompositions:

23 + 31514479 = 31514502
29 + 31514473 = 31514502
53 + 31514449 = 31514502
73 + 31514429 = 31514502
79 + 31514423 = 31514502
83 + 31514419 = 31514502
101 + 31514401 = 31514502
193 + 31514309 = 31514502

Showing the first eight; more decompositions exist.
