Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610162, here are decompositions:

19 + 31610143 = 31610162
79 + 31610083 = 31610162
139 + 31610023 = 31610162
151 + 31610011 = 31610162
229 + 31609933 = 31610162
313 + 31609849 = 31610162
349 + 31609813 = 31610162
421 + 31609741 = 31610162

Showing the first eight; more decompositions exist.
