Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470774, here are decompositions:

53 + 31470721 = 31470774
73 + 31470701 = 31470774
113 + 31470661 = 31470774
151 + 31470623 = 31470774
193 + 31470581 = 31470774
211 + 31470563 = 31470774
227 + 31470547 = 31470774
331 + 31470443 = 31470774

Showing the first eight; more decompositions exist.
