Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514492, here are decompositions:

13 + 31514479 = 31514492
19 + 31514473 = 31514492
43 + 31514449 = 31514492
73 + 31514419 = 31514492
271 + 31514221 = 31514492
349 + 31514143 = 31514492
379 + 31514113 = 31514492
433 + 31514059 = 31514492

Showing the first eight; more decompositions exist.
