Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467490, here are decompositions:

23 + 31467467 = 31467490
53 + 31467437 = 31467490
59 + 31467431 = 31467490
71 + 31467419 = 31467490
101 + 31467389 = 31467490
179 + 31467311 = 31467490
239 + 31467251 = 31467490
401 + 31467089 = 31467490

Showing the first eight; more decompositions exist.
