Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472822, here are decompositions:

211 + 31472611 = 31472822
373 + 31472449 = 31472822
463 + 31472359 = 31472822
613 + 31472209 = 31472822
631 + 31472191 = 31472822
643 + 31472179 = 31472822
673 + 31472149 = 31472822
691 + 31472131 = 31472822

Showing the first eight; more decompositions exist.
