Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611244, here are decompositions:

107 + 31611137 = 31611244
131 + 31611113 = 31611244
227 + 31611017 = 31611244
233 + 31611011 = 31611244
503 + 31610741 = 31611244
521 + 31610723 = 31611244
683 + 31610561 = 31611244
881 + 31610363 = 31611244

Showing the first eight; more decompositions exist.
