Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467468, here are decompositions:

31 + 31467437 = 31467468
37 + 31467431 = 31467468
79 + 31467389 = 31467468
101 + 31467367 = 31467468
139 + 31467329 = 31467468
157 + 31467311 = 31467468
167 + 31467301 = 31467468
239 + 31467229 = 31467468

Showing the first eight; more decompositions exist.
