Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611164, here are decompositions:

37 + 31611127 = 31611164
97 + 31611067 = 31611164
127 + 31611037 = 31611164
271 + 31610893 = 31611164
373 + 31610791 = 31611164
457 + 31610707 = 31611164
523 + 31610641 = 31611164
577 + 31610587 = 31611164

Showing the first eight; more decompositions exist.
