Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476080, here are decompositions:

7 + 31476073 = 31476080
67 + 31476013 = 31476080
127 + 31475953 = 31476080
151 + 31475929 = 31476080
283 + 31475797 = 31476080
331 + 31475749 = 31476080
367 + 31475713 = 31476080
397 + 31475683 = 31476080

Showing the first eight; more decompositions exist.
