Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464226, here are decompositions:

83 + 31464143 = 31464226
89 + 31464137 = 31464226
179 + 31464047 = 31464226
263 + 31463963 = 31464226
317 + 31463909 = 31464226
347 + 31463879 = 31464226
383 + 31463843 = 31464226
419 + 31463807 = 31464226

Showing the first eight; more decompositions exist.
