Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592556, here are decompositions:

5 + 31592551 = 31592556
67 + 31592489 = 31592556
89 + 31592467 = 31592556
103 + 31592453 = 31592556
109 + 31592447 = 31592556
139 + 31592417 = 31592556
167 + 31592389 = 31592556
179 + 31592377 = 31592556

Showing the first eight; more decompositions exist.
