Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613092, here are decompositions:

101 + 31612991 = 31613092
131 + 31612961 = 31613092
179 + 31612913 = 31613092
239 + 31612853 = 31613092
353 + 31612739 = 31613092
359 + 31612733 = 31613092
431 + 31612661 = 31613092
503 + 31612589 = 31613092

Showing the first eight; more decompositions exist.
