Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562026, here are decompositions:

3 + 31562023 = 31562026
17 + 31562009 = 31562026
53 + 31561973 = 31562026
59 + 31561967 = 31562026
107 + 31561919 = 31562026
179 + 31561847 = 31562026
383 + 31561643 = 31562026
449 + 31561577 = 31562026

Showing the first eight; more decompositions exist.
