Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562610, here are decompositions:

7 + 31562603 = 31562610
17 + 31562593 = 31562610
43 + 31562567 = 31562610
59 + 31562551 = 31562610
67 + 31562543 = 31562610
109 + 31562501 = 31562610
127 + 31562483 = 31562610
179 + 31562431 = 31562610

Showing the first eight; more decompositions exist.
