Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504886, here are decompositions:

3 + 31504883 = 31504886
13 + 31504873 = 31504886
67 + 31504819 = 31504886
103 + 31504783 = 31504886
139 + 31504747 = 31504886
313 + 31504573 = 31504886
433 + 31504453 = 31504886
499 + 31504387 = 31504886

Showing the first eight; more decompositions exist.
