Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467632, here are decompositions:

43 + 31467589 = 31467632
61 + 31467571 = 31467632
73 + 31467559 = 31467632
151 + 31467481 = 31467632
199 + 31467433 = 31467632
331 + 31467301 = 31467632
373 + 31467259 = 31467632
433 + 31467199 = 31467632

Showing the first eight; more decompositions exist.
