Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615614, here are decompositions:

5 + 31615609 = 31615614
11 + 31615603 = 31615614
31 + 31615583 = 31615614
71 + 31615543 = 31615614
131 + 31615483 = 31615614
137 + 31615477 = 31615614
197 + 31615417 = 31615614
211 + 31615403 = 31615614

Showing the first eight; more decompositions exist.
