Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547234, here are decompositions:

3 + 31547231 = 31547234
31 + 31547203 = 31547234
73 + 31547161 = 31547234
157 + 31547077 = 31547234
373 + 31546861 = 31547234
421 + 31546813 = 31547234
571 + 31546663 = 31547234
577 + 31546657 = 31547234

Showing the first eight; more decompositions exist.
