Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612394, here are decompositions:

3 + 31612391 = 31612394
13 + 31612381 = 31612394
31 + 31612363 = 31612394
43 + 31612351 = 31612394
193 + 31612201 = 31612394
313 + 31612081 = 31612394
397 + 31611997 = 31612394
487 + 31611907 = 31612394

Showing the first eight; more decompositions exist.
