Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592538, here are decompositions:

7 + 31592531 = 31592538
71 + 31592467 = 31592538
101 + 31592437 = 31592538
127 + 31592411 = 31592538
149 + 31592389 = 31592538
181 + 31592357 = 31592538
191 + 31592347 = 31592538
227 + 31592311 = 31592538

Showing the first eight; more decompositions exist.
