Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465002, here are decompositions:

11 + 31464991 = 31465002
29 + 31464973 = 31465002
61 + 31464941 = 31465002
181 + 31464821 = 31465002
193 + 31464809 = 31465002
271 + 31464731 = 31465002
293 + 31464709 = 31465002
353 + 31464649 = 31465002

Showing the first eight; more decompositions exist.
