Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494084, here are decompositions:

5 + 31494079 = 31494084
31 + 31494053 = 31494084
43 + 31494041 = 31494084
101 + 31493983 = 31494084
157 + 31493927 = 31494084
227 + 31493857 = 31494084
233 + 31493851 = 31494084
263 + 31493821 = 31494084

Showing the first eight; more decompositions exist.
