Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613260, here are decompositions:

11 + 31613249 = 31613260
17 + 31613243 = 31613260
89 + 31613171 = 31613260
233 + 31613027 = 31613260
269 + 31612991 = 31613260
347 + 31612913 = 31613260
521 + 31612739 = 31613260
593 + 31612667 = 31613260

Showing the first eight; more decompositions exist.
