Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590148, here are decompositions:

11 + 31590137 = 31590148
59 + 31590089 = 31590148
137 + 31590011 = 31590148
167 + 31589981 = 31590148
257 + 31589891 = 31590148
281 + 31589867 = 31590148
389 + 31589759 = 31590148
587 + 31589561 = 31590148

Showing the first eight; more decompositions exist.
