Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619734, here are decompositions:

11 + 31619723 = 31619734
17 + 31619717 = 31619734
131 + 31619603 = 31619734
173 + 31619561 = 31619734
191 + 31619543 = 31619734
233 + 31619501 = 31619734
347 + 31619387 = 31619734
467 + 31619267 = 31619734

Showing the first eight; more decompositions exist.
