Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504964, here are decompositions:

13 + 31504951 = 31504964
61 + 31504903 = 31504964
163 + 31504801 = 31504964
181 + 31504783 = 31504964
313 + 31504651 = 31504964
373 + 31504591 = 31504964
397 + 31504567 = 31504964
577 + 31504387 = 31504964

Showing the first eight; more decompositions exist.
