Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456132, here are decompositions:

11 + 31456121 = 31456132
53 + 31456079 = 31456132
173 + 31455959 = 31456132
263 + 31455869 = 31456132
311 + 31455821 = 31456132
419 + 31455713 = 31456132
431 + 31455701 = 31456132
509 + 31455623 = 31456132

Showing the first eight; more decompositions exist.
