Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464122, here are decompositions:

43 + 31464079 = 31464122
61 + 31464061 = 31464122
163 + 31463959 = 31464122
181 + 31463941 = 31464122
211 + 31463911 = 31464122
229 + 31463893 = 31464122
379 + 31463743 = 31464122
409 + 31463713 = 31464122

Showing the first eight; more decompositions exist.
