Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465032, here are decompositions:

29 + 31465003 = 31465032
41 + 31464991 = 31465032
59 + 31464973 = 31465032
149 + 31464883 = 31465032
211 + 31464821 = 31465032
223 + 31464809 = 31465032
251 + 31464781 = 31465032
331 + 31464701 = 31465032

Showing the first eight; more decompositions exist.
