Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471260, here are decompositions:

43 + 31471217 = 31471260
47 + 31471213 = 31471260
53 + 31471207 = 31471260
89 + 31471171 = 31471260
113 + 31471147 = 31471260
137 + 31471123 = 31471260
151 + 31471109 = 31471260
167 + 31471093 = 31471260

Showing the first eight; more decompositions exist.
