Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559036, here are decompositions:

43 + 31558993 = 31559036
73 + 31558963 = 31559036
79 + 31558957 = 31559036
97 + 31558939 = 31559036
109 + 31558927 = 31559036
139 + 31558897 = 31559036
193 + 31558843 = 31559036
277 + 31558759 = 31559036

Showing the first eight; more decompositions exist.
