Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615734, here are decompositions:

5 + 31615729 = 31615734
23 + 31615711 = 31615734
71 + 31615663 = 31615734
83 + 31615651 = 31615734
131 + 31615603 = 31615734
151 + 31615583 = 31615734
191 + 31615543 = 31615734
251 + 31615483 = 31615734

Showing the first eight; more decompositions exist.
