Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592622, here are decompositions:

23 + 31592599 = 31592622
71 + 31592551 = 31592622
199 + 31592423 = 31592622
211 + 31592411 = 31592622
233 + 31592389 = 31592622
311 + 31592311 = 31592622
331 + 31592291 = 31592622
409 + 31592213 = 31592622

Showing the first eight; more decompositions exist.
