Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465092, here are decompositions:

23 + 31465069 = 31465092
31 + 31465061 = 31465092
53 + 31465039 = 31465092
59 + 31465033 = 31465092
89 + 31465003 = 31465092
101 + 31464991 = 31465092
151 + 31464941 = 31465092
271 + 31464821 = 31465092

Showing the first eight; more decompositions exist.
