Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612952, here are decompositions:

13 + 31612939 = 31612952
61 + 31612891 = 31612952
79 + 31612873 = 31612952
193 + 31612759 = 31612952
199 + 31612753 = 31612952
223 + 31612729 = 31612952
331 + 31612621 = 31612952
379 + 31612573 = 31612952

Showing the first eight; more decompositions exist.
