Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468086, here are decompositions:

19 + 31468067 = 31468086
59 + 31468027 = 31468086
73 + 31468013 = 31468086
103 + 31467983 = 31468086
137 + 31467949 = 31468086
149 + 31467937 = 31468086
193 + 31467893 = 31468086
233 + 31467853 = 31468086

Showing the first eight; more decompositions exist.
