Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514546, here are decompositions:

13 + 31514533 = 31514546
67 + 31514479 = 31514546
73 + 31514473 = 31514546
97 + 31514449 = 31514546
127 + 31514419 = 31514546
307 + 31514239 = 31514546
397 + 31514149 = 31514546
433 + 31514113 = 31514546

Showing the first eight; more decompositions exist.
