Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610576, here are decompositions:

3 + 31610573 = 31610576
7 + 31610569 = 31610576
13 + 31610563 = 31610576
37 + 31610539 = 31610576
73 + 31610503 = 31610576
139 + 31610437 = 31610576
163 + 31610413 = 31610576
223 + 31610353 = 31610576

Showing the first eight; more decompositions exist.
