Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514636, here are decompositions:

7 + 31514629 = 31514636
37 + 31514599 = 31514636
103 + 31514533 = 31514636
157 + 31514479 = 31514636
163 + 31514473 = 31514636
397 + 31514239 = 31514636
487 + 31514149 = 31514636
523 + 31514113 = 31514636

Showing the first eight; more decompositions exist.
