Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592522, here are decompositions:

211 + 31592311 = 31592522
349 + 31592173 = 31592522
373 + 31592149 = 31592522
523 + 31591999 = 31592522
613 + 31591909 = 31592522
739 + 31591783 = 31592522
811 + 31591711 = 31592522
919 + 31591603 = 31592522

Showing the first eight; more decompositions exist.
