Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589070, here are decompositions:

13 + 31589057 = 31589070
43 + 31589027 = 31589070
53 + 31589017 = 31589070
59 + 31589011 = 31589070
113 + 31588957 = 31589070
127 + 31588943 = 31589070
137 + 31588933 = 31589070
173 + 31588897 = 31589070

Showing the first eight; more decompositions exist.
