Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562036, here are decompositions:

3 + 31562033 = 31562036
13 + 31562023 = 31562036
19 + 31562017 = 31562036
43 + 31561993 = 31562036
67 + 31561969 = 31562036
97 + 31561939 = 31562036
109 + 31561927 = 31562036
229 + 31561807 = 31562036

Showing the first eight; more decompositions exist.
