Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624416, here are decompositions:

29 + 31624387 = 31624416
53 + 31624363 = 31624416
59 + 31624357 = 31624416
67 + 31624349 = 31624416
73 + 31624343 = 31624416
79 + 31624337 = 31624416
139 + 31624277 = 31624416
199 + 31624217 = 31624416

Showing the first eight; more decompositions exist.
