Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467842, here are decompositions:

13 + 31467829 = 31467842
31 + 31467811 = 31467842
79 + 31467763 = 31467842
151 + 31467691 = 31467842
271 + 31467571 = 31467842
283 + 31467559 = 31467842
409 + 31467433 = 31467842
541 + 31467301 = 31467842

Showing the first eight; more decompositions exist.
