Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611796, here are decompositions:

59 + 31611737 = 31611796
137 + 31611659 = 31611796
149 + 31611647 = 31611796
179 + 31611617 = 31611796
257 + 31611539 = 31611796
269 + 31611527 = 31611796
467 + 31611329 = 31611796
659 + 31611137 = 31611796

Showing the first eight; more decompositions exist.
