Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467636, here are decompositions:

43 + 31467593 = 31467636
47 + 31467589 = 31467636
97 + 31467539 = 31467636
103 + 31467533 = 31467636
127 + 31467509 = 31467636
139 + 31467497 = 31467636
199 + 31467437 = 31467636
269 + 31467367 = 31467636

Showing the first eight; more decompositions exist.
