Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626900, here are decompositions:

7 + 31626893 = 31626900
17 + 31626883 = 31626900
31 + 31626869 = 31626900
43 + 31626857 = 31626900
59 + 31626841 = 31626900
61 + 31626839 = 31626900
73 + 31626827 = 31626900
103 + 31626797 = 31626900

Showing the first eight; more decompositions exist.
