Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465064, here are decompositions:

3 + 31465061 = 31465064
31 + 31465033 = 31465064
61 + 31465003 = 31465064
73 + 31464991 = 31465064
97 + 31464967 = 31465064
181 + 31464883 = 31465064
277 + 31464787 = 31465064
283 + 31464781 = 31465064

Showing the first eight; more decompositions exist.
