Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610490, here are decompositions:

53 + 31610437 = 31610490
97 + 31610393 = 31610490
101 + 31610389 = 31610490
127 + 31610363 = 31610490
137 + 31610353 = 31610490
151 + 31610339 = 31610490
157 + 31610333 = 31610490
173 + 31610317 = 31610490

Showing the first eight; more decompositions exist.
