Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467628, here are decompositions:

41 + 31467587 = 31467628
89 + 31467539 = 31467628
131 + 31467497 = 31467628
191 + 31467437 = 31467628
197 + 31467431 = 31467628
239 + 31467389 = 31467628
281 + 31467347 = 31467628
317 + 31467311 = 31467628

Showing the first eight; more decompositions exist.
