Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564652, here are decompositions:

3 + 31564649 = 31564652
13 + 31564639 = 31564652
61 + 31564591 = 31564652
151 + 31564501 = 31564652
193 + 31564459 = 31564652
331 + 31564321 = 31564652
409 + 31564243 = 31564652
523 + 31564129 = 31564652

Showing the first eight; more decompositions exist.
