Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467442, here are decompositions:

5 + 31467437 = 31467442
11 + 31467431 = 31467442
23 + 31467419 = 31467442
53 + 31467389 = 31467442
113 + 31467329 = 31467442
131 + 31467311 = 31467442
191 + 31467251 = 31467442
239 + 31467203 = 31467442

Showing the first eight; more decompositions exist.
