Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514576, here are decompositions:

3 + 31514573 = 31514576
43 + 31514533 = 31514576
97 + 31514479 = 31514576
103 + 31514473 = 31514576
127 + 31514449 = 31514576
157 + 31514419 = 31514576
337 + 31514239 = 31514576
433 + 31514143 = 31514576

Showing the first eight; more decompositions exist.
