Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467206, here are decompositions:

3 + 31467203 = 31467206
7 + 31467199 = 31467206
37 + 31467169 = 31467206
73 + 31467133 = 31467206
79 + 31467127 = 31467206
103 + 31467103 = 31467206
139 + 31467067 = 31467206
229 + 31466977 = 31467206

Showing the first eight; more decompositions exist.
