Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476210, here are decompositions:

23 + 31476187 = 31476210
41 + 31476169 = 31476210
53 + 31476157 = 31476210
61 + 31476149 = 31476210
67 + 31476143 = 31476210
97 + 31476113 = 31476210
113 + 31476097 = 31476210
137 + 31476073 = 31476210

Showing the first eight; more decompositions exist.
