Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612844, here are decompositions:

13 + 31612831 = 31612844
97 + 31612747 = 31612844
181 + 31612663 = 31612844
223 + 31612621 = 31612844
271 + 31612573 = 31612844
313 + 31612531 = 31612844
331 + 31612513 = 31612844
421 + 31612423 = 31612844

Showing the first eight; more decompositions exist.
