Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612774, here are decompositions:

41 + 31612733 = 31612774
47 + 31612727 = 31612774
107 + 31612667 = 31612774
113 + 31612661 = 31612774
191 + 31612583 = 31612774
227 + 31612547 = 31612774
293 + 31612481 = 31612774
383 + 31612391 = 31612774

Showing the first eight; more decompositions exist.
