Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610474, here are decompositions:

37 + 31610437 = 31610474
61 + 31610413 = 31610474
157 + 31610317 = 31610474
277 + 31610197 = 31610474
331 + 31610143 = 31610474
367 + 31610107 = 31610474
463 + 31610011 = 31610474
541 + 31609933 = 31610474

Showing the first eight; more decompositions exist.
