Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467986, here are decompositions:

3 + 31467983 = 31467986
19 + 31467967 = 31467986
37 + 31467949 = 31467986
139 + 31467847 = 31467986
157 + 31467829 = 31467986
223 + 31467763 = 31467986
397 + 31467589 = 31467986
619 + 31467367 = 31467986

Showing the first eight; more decompositions exist.
