Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611962, here are decompositions:

79 + 31611883 = 31611962
229 + 31611733 = 31611962
379 + 31611583 = 31611962
409 + 31611553 = 31611962
523 + 31611439 = 31611962
643 + 31611319 = 31611962
661 + 31611301 = 31611962
691 + 31611271 = 31611962

Showing the first eight; more decompositions exist.
