Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467836, here are decompositions:

7 + 31467829 = 31467836
73 + 31467763 = 31467836
109 + 31467727 = 31467836
277 + 31467559 = 31467836
577 + 31467259 = 31467836
607 + 31467229 = 31467836
709 + 31467127 = 31467836
733 + 31467103 = 31467836

Showing the first eight; more decompositions exist.
