Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465010, here are decompositions:

7 + 31465003 = 31465010
19 + 31464991 = 31465010
37 + 31464973 = 31465010
43 + 31464967 = 31465010
127 + 31464883 = 31465010
223 + 31464787 = 31465010
229 + 31464781 = 31465010
433 + 31464577 = 31465010

Showing the first eight; more decompositions exist.
