Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626100, here are decompositions:

47 + 31626053 = 31626100
59 + 31626041 = 31626100
89 + 31626011 = 31626100
113 + 31625987 = 31626100
131 + 31625969 = 31626100
137 + 31625963 = 31626100
251 + 31625849 = 31626100
257 + 31625843 = 31626100

Showing the first eight; more decompositions exist.
