Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476338, here are decompositions:

151 + 31476187 = 31476338
181 + 31476157 = 31476338
241 + 31476097 = 31476338
307 + 31476031 = 31476338
409 + 31475929 = 31476338
541 + 31475797 = 31476338
661 + 31475677 = 31476338
727 + 31475611 = 31476338

Showing the first eight; more decompositions exist.
