Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514562, here are decompositions:

11 + 31514551 = 31514562
29 + 31514533 = 31514562
83 + 31514479 = 31514562
89 + 31514473 = 31514562
113 + 31514449 = 31514562
139 + 31514423 = 31514562
271 + 31514291 = 31514562
419 + 31514143 = 31514562

Showing the first eight; more decompositions exist.
