Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464682, here are decompositions:

101 + 31464581 = 31464682
173 + 31464509 = 31464682
239 + 31464443 = 31464682
281 + 31464401 = 31464682
401 + 31464281 = 31464682
449 + 31464233 = 31464682
719 + 31463963 = 31464682
761 + 31463921 = 31464682

Showing the first eight; more decompositions exist.
