Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610546, here are decompositions:

7 + 31610539 = 31610546
43 + 31610503 = 31610546
109 + 31610437 = 31610546
157 + 31610389 = 31610546
193 + 31610353 = 31610546
229 + 31610317 = 31610546
277 + 31610269 = 31610546
349 + 31610197 = 31610546

Showing the first eight; more decompositions exist.
