Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537070, here are decompositions:

31 + 31537039 = 31537070
43 + 31537027 = 31537070
67 + 31537003 = 31537070
79 + 31536991 = 31537070
127 + 31536943 = 31537070
199 + 31536871 = 31537070
223 + 31536847 = 31537070
241 + 31536829 = 31537070

Showing the first eight; more decompositions exist.
