Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465074, here are decompositions:

5 + 31465069 = 31465074
13 + 31465061 = 31465074
41 + 31465033 = 31465074
71 + 31465003 = 31465074
83 + 31464991 = 31465074
101 + 31464973 = 31465074
107 + 31464967 = 31465074
127 + 31464947 = 31465074

Showing the first eight; more decompositions exist.
