Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551060, here are decompositions:

41 + 31551019 = 31551060
61 + 31550999 = 31551060
67 + 31550993 = 31551060
83 + 31550977 = 31551060
113 + 31550947 = 31551060
137 + 31550923 = 31551060
139 + 31550921 = 31551060
181 + 31550879 = 31551060

Showing the first eight; more decompositions exist.
