Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485606, here are decompositions:

7 + 31485599 = 31485606
23 + 31485583 = 31485606
73 + 31485533 = 31485606
109 + 31485497 = 31485606
157 + 31485449 = 31485606
179 + 31485427 = 31485606
199 + 31485407 = 31485606
223 + 31485383 = 31485606

Showing the first eight; more decompositions exist.
