Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625714, here are decompositions:

61 + 31625653 = 31625714
67 + 31625647 = 31625714
97 + 31625617 = 31625714
151 + 31625563 = 31625714
283 + 31625431 = 31625714
313 + 31625401 = 31625714
331 + 31625383 = 31625714
433 + 31625281 = 31625714

Showing the first eight; more decompositions exist.
