Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592486, here are decompositions:

19 + 31592467 = 31592486
97 + 31592389 = 31592486
109 + 31592377 = 31592486
139 + 31592347 = 31592486
229 + 31592257 = 31592486
283 + 31592203 = 31592486
313 + 31592173 = 31592486
337 + 31592149 = 31592486

Showing the first eight; more decompositions exist.
