Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569416, here are decompositions:

37 + 31569379 = 31569416
79 + 31569337 = 31569416
97 + 31569319 = 31569416
139 + 31569277 = 31569416
157 + 31569259 = 31569416
223 + 31569193 = 31569416
367 + 31569049 = 31569416
379 + 31569037 = 31569416

Showing the first eight; more decompositions exist.
