Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465152, here are decompositions:

23 + 31465129 = 31465152
29 + 31465123 = 31465152
41 + 31465111 = 31465152
53 + 31465099 = 31465152
83 + 31465069 = 31465152
113 + 31465039 = 31465152
149 + 31465003 = 31465152
179 + 31464973 = 31465152

Showing the first eight; more decompositions exist.
