Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592472, here are decompositions:

5 + 31592467 = 31592472
19 + 31592453 = 31592472
61 + 31592411 = 31592472
83 + 31592389 = 31592472
103 + 31592369 = 31592472
181 + 31592291 = 31592472
269 + 31592203 = 31592472
311 + 31592161 = 31592472

Showing the first eight; more decompositions exist.
