Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624894, here are decompositions:

113 + 31624781 = 31624894
131 + 31624763 = 31624894
233 + 31624661 = 31624894
251 + 31624643 = 31624894
263 + 31624631 = 31624894
281 + 31624613 = 31624894
347 + 31624547 = 31624894
383 + 31624511 = 31624894

Showing the first eight; more decompositions exist.
