Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485414, here are decompositions:

7 + 31485407 = 31485414
13 + 31485401 = 31485414
17 + 31485397 = 31485414
31 + 31485383 = 31485414
61 + 31485353 = 31485414
73 + 31485341 = 31485414
101 + 31485313 = 31485414
113 + 31485301 = 31485414

Showing the first eight; more decompositions exist.
