Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592560, here are decompositions:

3 + 31592557 = 31592560
29 + 31592531 = 31592560
71 + 31592489 = 31592560
107 + 31592453 = 31592560
113 + 31592447 = 31592560
137 + 31592423 = 31592560
149 + 31592411 = 31592560
191 + 31592369 = 31592560

Showing the first eight; more decompositions exist.
