Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465112, here are decompositions:

13 + 31465099 = 31465112
43 + 31465069 = 31465112
73 + 31465039 = 31465112
79 + 31465033 = 31465112
109 + 31465003 = 31465112
139 + 31464973 = 31465112
229 + 31464883 = 31465112
331 + 31464781 = 31465112

Showing the first eight; more decompositions exist.
