Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467390, here are decompositions:

23 + 31467367 = 31467390
43 + 31467347 = 31467390
61 + 31467329 = 31467390
79 + 31467311 = 31467390
89 + 31467301 = 31467390
131 + 31467259 = 31467390
139 + 31467251 = 31467390
191 + 31467199 = 31467390

Showing the first eight; more decompositions exist.
