Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467870, here are decompositions:

17 + 31467853 = 31467870
23 + 31467847 = 31467870
41 + 31467829 = 31467870
59 + 31467811 = 31467870
61 + 31467809 = 31467870
103 + 31467767 = 31467870
107 + 31467763 = 31467870
149 + 31467721 = 31467870

Showing the first eight; more decompositions exist.
