Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485594, here are decompositions:

11 + 31485583 = 31485594
53 + 31485541 = 31485594
61 + 31485533 = 31485594
97 + 31485497 = 31485594
163 + 31485431 = 31485594
167 + 31485427 = 31485594
193 + 31485401 = 31485594
197 + 31485397 = 31485594

Showing the first eight; more decompositions exist.
