Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465432, here are decompositions:

41 + 31465391 = 31465432
239 + 31465193 = 31465432
491 + 31464941 = 31465432
701 + 31464731 = 31465432
1031 + 31464401 = 31465432
1091 + 31464341 = 31465432
1151 + 31464281 = 31465432
1163 + 31464269 = 31465432

Showing the first eight; more decompositions exist.
