Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562634, here are decompositions:

7 + 31562627 = 31562634
11 + 31562623 = 31562634
13 + 31562621 = 31562634
17 + 31562617 = 31562634
23 + 31562611 = 31562634
31 + 31562603 = 31562634
41 + 31562593 = 31562634
67 + 31562567 = 31562634

Showing the first eight; more decompositions exist.
