Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615674, here are decompositions:

5 + 31615669 = 31615674
11 + 31615663 = 31615674
23 + 31615651 = 31615674
71 + 31615603 = 31615674
131 + 31615543 = 31615674
191 + 31615483 = 31615674
197 + 31615477 = 31615674
257 + 31615417 = 31615674

Showing the first eight; more decompositions exist.
