Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612994, here are decompositions:

3 + 31612991 = 31612994
13 + 31612981 = 31612994
43 + 31612951 = 31612994
103 + 31612891 = 31612994
163 + 31612831 = 31612994
241 + 31612753 = 31612994
331 + 31612663 = 31612994
367 + 31612627 = 31612994

Showing the first eight; more decompositions exist.
