Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611752, here are decompositions:

19 + 31611733 = 31611752
43 + 31611709 = 31611752
79 + 31611673 = 31611752
199 + 31611553 = 31611752
313 + 31611439 = 31611752
349 + 31611403 = 31611752
373 + 31611379 = 31611752
433 + 31611319 = 31611752

Showing the first eight; more decompositions exist.
