Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610892, here are decompositions:

101 + 31610791 = 31610892
113 + 31610779 = 31610892
151 + 31610741 = 31610892
163 + 31610729 = 31610892
251 + 31610641 = 31610892
263 + 31610629 = 31610892
311 + 31610581 = 31610892
331 + 31610561 = 31610892

Showing the first eight; more decompositions exist.
