Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485036, here are decompositions:

5 + 31485031 = 31485036
13 + 31485023 = 31485036
17 + 31485019 = 31485036
19 + 31485017 = 31485036
43 + 31484993 = 31485036
47 + 31484989 = 31485036
173 + 31484863 = 31485036
197 + 31484839 = 31485036

Showing the first eight; more decompositions exist.
