Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465262, here are decompositions:

19 + 31465243 = 31465262
79 + 31465183 = 31465262
109 + 31465153 = 31465262
139 + 31465123 = 31465262
151 + 31465111 = 31465262
163 + 31465099 = 31465262
193 + 31465069 = 31465262
223 + 31465039 = 31465262

Showing the first eight; more decompositions exist.
