Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611036, here are decompositions:

7 + 31611029 = 31611036
13 + 31611023 = 31611036
19 + 31611017 = 31611036
257 + 31610779 = 31611036
263 + 31610773 = 31611036
307 + 31610729 = 31611036
313 + 31610723 = 31611036
397 + 31610639 = 31611036

Showing the first eight; more decompositions exist.
