Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562664, here are decompositions:

37 + 31562627 = 31562664
41 + 31562623 = 31562664
43 + 31562621 = 31562664
47 + 31562617 = 31562664
53 + 31562611 = 31562664
61 + 31562603 = 31562664
71 + 31562593 = 31562664
97 + 31562567 = 31562664

Showing the first eight; more decompositions exist.
