Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467330, here are decompositions:

19 + 31467311 = 31467330
29 + 31467301 = 31467330
71 + 31467259 = 31467330
79 + 31467251 = 31467330
101 + 31467229 = 31467330
127 + 31467203 = 31467330
131 + 31467199 = 31467330
149 + 31467181 = 31467330

Showing the first eight; more decompositions exist.
