Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504910, here are decompositions:

7 + 31504903 = 31504910
37 + 31504873 = 31504910
109 + 31504801 = 31504910
127 + 31504783 = 31504910
163 + 31504747 = 31504910
337 + 31504573 = 31504910
457 + 31504453 = 31504910
523 + 31504387 = 31504910

Showing the first eight; more decompositions exist.
