Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477162, here are decompositions:

83 + 31477079 = 31477162
281 + 31476881 = 31477162
419 + 31476743 = 31477162
569 + 31476593 = 31477162
653 + 31476509 = 31477162
701 + 31476461 = 31477162
809 + 31476353 = 31477162
911 + 31476251 = 31477162

Showing the first eight; more decompositions exist.
