Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485696, here are decompositions:

43 + 31485653 = 31485696
97 + 31485599 = 31485696
113 + 31485583 = 31485696
163 + 31485533 = 31485696
199 + 31485497 = 31485696
223 + 31485473 = 31485696
269 + 31485427 = 31485696
313 + 31485383 = 31485696

Showing the first eight; more decompositions exist.
