Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610354, here are decompositions:

37 + 31610317 = 31610354
67 + 31610287 = 31610354
157 + 31610197 = 31610354
211 + 31610143 = 31610354
241 + 31610113 = 31610354
271 + 31610083 = 31610354
331 + 31610023 = 31610354
397 + 31609957 = 31610354

Showing the first eight; more decompositions exist.
