Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562624, here are decompositions:

3 + 31562621 = 31562624
7 + 31562617 = 31562624
13 + 31562611 = 31562624
31 + 31562593 = 31562624
73 + 31562551 = 31562624
157 + 31562467 = 31562624
193 + 31562431 = 31562624
277 + 31562347 = 31562624

Showing the first eight; more decompositions exist.
