Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562682, here are decompositions:

5 + 31562677 = 31562682
59 + 31562623 = 31562682
61 + 31562621 = 31562682
71 + 31562611 = 31562682
79 + 31562603 = 31562682
89 + 31562593 = 31562682
131 + 31562551 = 31562682
139 + 31562543 = 31562682

Showing the first eight; more decompositions exist.
