Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504906, here are decompositions:

3 + 31504903 = 31504906
23 + 31504883 = 31504906
107 + 31504799 = 31504906
239 + 31504667 = 31504906
359 + 31504547 = 31504906
467 + 31504439 = 31504906
677 + 31504229 = 31504906
773 + 31504133 = 31504906

Showing the first eight; more decompositions exist.
