Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624954, here are decompositions:

3 + 31624951 = 31624954
47 + 31624907 = 31624954
173 + 31624781 = 31624954
191 + 31624763 = 31624954
281 + 31624673 = 31624954
293 + 31624661 = 31624954
311 + 31624643 = 31624954
443 + 31624511 = 31624954

Showing the first eight; more decompositions exist.
