Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611360, here are decompositions:

19 + 31611341 = 31611360
31 + 31611329 = 31611360
37 + 31611323 = 31611360
41 + 31611319 = 31611360
59 + 31611301 = 31611360
61 + 31611299 = 31611360
89 + 31611271 = 31611360
173 + 31611187 = 31611360

Showing the first eight; more decompositions exist.
