Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592394, here are decompositions:

5 + 31592389 = 31592394
17 + 31592377 = 31592394
37 + 31592357 = 31592394
47 + 31592347 = 31592394
83 + 31592311 = 31592394
103 + 31592291 = 31592394
137 + 31592257 = 31592394
181 + 31592213 = 31592394

Showing the first eight; more decompositions exist.
