Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465292, here are decompositions:

3 + 31465289 = 31465292
109 + 31465183 = 31465292
139 + 31465153 = 31465292
163 + 31465129 = 31465292
181 + 31465111 = 31465292
193 + 31465099 = 31465292
223 + 31465069 = 31465292
409 + 31464883 = 31465292

Showing the first eight; more decompositions exist.
