Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467754, here are decompositions:

107 + 31467647 = 31467754
167 + 31467587 = 31467754
251 + 31467503 = 31467754
257 + 31467497 = 31467754
317 + 31467437 = 31467754
443 + 31467311 = 31467754
503 + 31467251 = 31467754
587 + 31467167 = 31467754

Showing the first eight; more decompositions exist.
