Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467080, here are decompositions:

13 + 31467067 = 31467080
103 + 31466977 = 31467080
181 + 31466899 = 31467080
223 + 31466857 = 31467080
331 + 31466749 = 31467080
349 + 31466731 = 31467080
367 + 31466713 = 31467080
373 + 31466707 = 31467080

Showing the first eight; more decompositions exist.
