Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514606, here are decompositions:

7 + 31514599 = 31514606
73 + 31514533 = 31514606
127 + 31514479 = 31514606
157 + 31514449 = 31514606
367 + 31514239 = 31514606
457 + 31514149 = 31514606
463 + 31514143 = 31514606
547 + 31514059 = 31514606

Showing the first eight; more decompositions exist.
