Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592548, here are decompositions:

17 + 31592531 = 31592548
59 + 31592489 = 31592548
101 + 31592447 = 31592548
131 + 31592417 = 31592548
137 + 31592411 = 31592548
179 + 31592369 = 31592548
191 + 31592357 = 31592548
257 + 31592291 = 31592548

Showing the first eight; more decompositions exist.
