Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625434, here are decompositions:

3 + 31625431 = 31625434
23 + 31625411 = 31625434
41 + 31625393 = 31625434
53 + 31625381 = 31625434
83 + 31625351 = 31625434
131 + 31625303 = 31625434
173 + 31625261 = 31625434
653 + 31624781 = 31625434

Showing the first eight; more decompositions exist.
