Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485846, here are decompositions:

13 + 31485833 = 31485846
23 + 31485823 = 31485846
43 + 31485803 = 31485846
47 + 31485799 = 31485846
79 + 31485767 = 31485846
89 + 31485757 = 31485846
97 + 31485749 = 31485846
103 + 31485743 = 31485846

Showing the first eight; more decompositions exist.
