Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611362, here are decompositions:

43 + 31611319 = 31611362
61 + 31611301 = 31611362
199 + 31611163 = 31611362
313 + 31611049 = 31611362
571 + 31610791 = 31611362
733 + 31610629 = 31611362
823 + 31610539 = 31611362
859 + 31610503 = 31611362

Showing the first eight; more decompositions exist.
