Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562622, here are decompositions:

5 + 31562617 = 31562622
11 + 31562611 = 31562622
19 + 31562603 = 31562622
29 + 31562593 = 31562622
71 + 31562551 = 31562622
79 + 31562543 = 31562622
103 + 31562519 = 31562622
139 + 31562483 = 31562622

Showing the first eight; more decompositions exist.
