Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625510, here are decompositions:

3 + 31625507 = 31625510
43 + 31625467 = 31625510
79 + 31625431 = 31625510
109 + 31625401 = 31625510
127 + 31625383 = 31625510
229 + 31625281 = 31625510
331 + 31625179 = 31625510
379 + 31625131 = 31625510

Showing the first eight; more decompositions exist.
