Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611082, here are decompositions:

53 + 31611029 = 31611082
59 + 31611023 = 31611082
71 + 31611011 = 31611082
311 + 31610771 = 31611082
353 + 31610729 = 31611082
359 + 31610723 = 31611082
443 + 31610639 = 31611082
509 + 31610573 = 31611082

Showing the first eight; more decompositions exist.
