Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514520, here are decompositions:

7 + 31514513 = 31514520
41 + 31514479 = 31514520
43 + 31514477 = 31514520
47 + 31514473 = 31514520
71 + 31514449 = 31514520
97 + 31514423 = 31514520
101 + 31514419 = 31514520
211 + 31514309 = 31514520

Showing the first eight; more decompositions exist.
