Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504610, here are decompositions:

3 + 31504607 = 31504610
19 + 31504591 = 31504610
37 + 31504573 = 31504610
43 + 31504567 = 31504610
157 + 31504453 = 31504610
223 + 31504387 = 31504610
283 + 31504327 = 31504610
307 + 31504303 = 31504610

Showing the first eight; more decompositions exist.
