Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610690, here are decompositions:

61 + 31610629 = 31610690
103 + 31610587 = 31610690
109 + 31610581 = 31610690
127 + 31610563 = 31610690
151 + 31610539 = 31610690
277 + 31610413 = 31610690
337 + 31610353 = 31610690
373 + 31610317 = 31610690

Showing the first eight; more decompositions exist.
