Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619944, here are decompositions:

101 + 31619843 = 31619944
137 + 31619807 = 31619944
173 + 31619771 = 31619944
227 + 31619717 = 31619944
383 + 31619561 = 31619944
401 + 31619543 = 31619944
443 + 31619501 = 31619944
557 + 31619387 = 31619944

Showing the first eight; more decompositions exist.
