Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464130, here are decompositions:

83 + 31464047 = 31464130
167 + 31463963 = 31464130
233 + 31463897 = 31464130
239 + 31463891 = 31464130
251 + 31463879 = 31464130
281 + 31463849 = 31464130
449 + 31463681 = 31464130
641 + 31463489 = 31464130

Showing the first eight; more decompositions exist.
