Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615762, here are decompositions:

5 + 31615757 = 31615762
173 + 31615589 = 31615762
179 + 31615583 = 31615762
359 + 31615403 = 31615762
419 + 31615343 = 31615762
449 + 31615313 = 31615762
569 + 31615193 = 31615762
593 + 31615169 = 31615762

Showing the first eight; more decompositions exist.
