Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562028, here are decompositions:

5 + 31562023 = 31562028
11 + 31562017 = 31562028
19 + 31562009 = 31562028
59 + 31561969 = 31562028
61 + 31561967 = 31562028
89 + 31561939 = 31562028
101 + 31561927 = 31562028
109 + 31561919 = 31562028

Showing the first eight; more decompositions exist.
