Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463290, here are decompositions:

29 + 31463261 = 31463290
41 + 31463249 = 31463290
167 + 31463123 = 31463290
191 + 31463099 = 31463290
227 + 31463063 = 31463290
311 + 31462979 = 31463290
359 + 31462931 = 31463290
389 + 31462901 = 31463290

Showing the first eight; more decompositions exist.
