Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613554, here are decompositions:

3 + 31613551 = 31613554
41 + 31613513 = 31613554
113 + 31613441 = 31613554
197 + 31613357 = 31613554
263 + 31613291 = 31613554
311 + 31613243 = 31613554
383 + 31613171 = 31613554
563 + 31612991 = 31613554

Showing the first eight; more decompositions exist.
