Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465268, here are decompositions:

139 + 31465129 = 31465268
157 + 31465111 = 31465268
199 + 31465069 = 31465268
229 + 31465039 = 31465268
277 + 31464991 = 31465268
487 + 31464781 = 31465268
619 + 31464649 = 31465268
691 + 31464577 = 31465268

Showing the first eight; more decompositions exist.
