Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485534, here are decompositions:

37 + 31485497 = 31485534
61 + 31485473 = 31485534
103 + 31485431 = 31485534
107 + 31485427 = 31485534
127 + 31485407 = 31485534
137 + 31485397 = 31485534
151 + 31485383 = 31485534
181 + 31485353 = 31485534

Showing the first eight; more decompositions exist.
