Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622572, here are decompositions:

53 + 31622519 = 31622572
383 + 31622189 = 31622572
389 + 31622183 = 31622572
419 + 31622153 = 31622572
431 + 31622141 = 31622572
491 + 31622081 = 31622572
593 + 31621979 = 31622572
911 + 31621661 = 31622572

Showing the first eight; more decompositions exist.
