Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613302, here are decompositions:

11 + 31613291 = 31613302
53 + 31613249 = 31613302
59 + 31613243 = 31613302
131 + 31613171 = 31613302
311 + 31612991 = 31613302
389 + 31612913 = 31613302
449 + 31612853 = 31613302
563 + 31612739 = 31613302

Showing the first eight; more decompositions exist.
