Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466088, here are decompositions:

37 + 31466051 = 31466088
89 + 31465999 = 31466088
109 + 31465979 = 31466088
197 + 31465891 = 31466088
239 + 31465849 = 31466088
257 + 31465831 = 31466088
307 + 31465781 = 31466088
331 + 31465757 = 31466088

Showing the first eight; more decompositions exist.
