Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611598, here are decompositions:

17 + 31611581 = 31611598
59 + 31611539 = 31611598
71 + 31611527 = 31611598
89 + 31611509 = 31611598
131 + 31611467 = 31611598
257 + 31611341 = 31611598
269 + 31611329 = 31611598
461 + 31611137 = 31611598

Showing the first eight; more decompositions exist.
