Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610580, here are decompositions:

7 + 31610573 = 31610580
11 + 31610569 = 31610580
17 + 31610563 = 31610580
19 + 31610561 = 31610580
41 + 31610539 = 31610580
59 + 31610521 = 31610580
61 + 31610519 = 31610580
167 + 31610413 = 31610580

Showing the first eight; more decompositions exist.
