Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611254, here are decompositions:

67 + 31611187 = 31611254
127 + 31611127 = 31611254
211 + 31611043 = 31611254
463 + 31610791 = 31611254
547 + 31610707 = 31611254
613 + 31610641 = 31611254
673 + 31610581 = 31611254
691 + 31610563 = 31611254

Showing the first eight; more decompositions exist.
