Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31561062, here are decompositions:

19 + 31561043 = 31561062
59 + 31561003 = 31561062
61 + 31561001 = 31561062
79 + 31560983 = 31561062
83 + 31560979 = 31561062
151 + 31560911 = 31561062
191 + 31560871 = 31561062
193 + 31560869 = 31561062

Showing the first eight; more decompositions exist.
