Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467572, here are decompositions:

13 + 31467559 = 31467572
139 + 31467433 = 31467572
271 + 31467301 = 31467572
313 + 31467259 = 31467572
373 + 31467199 = 31467572
439 + 31467133 = 31467572
673 + 31466899 = 31467572
751 + 31466821 = 31467572

Showing the first eight; more decompositions exist.
