Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619754, here are decompositions:

13 + 31619741 = 31619754
31 + 31619723 = 31619754
37 + 31619717 = 31619754
41 + 31619713 = 31619754
71 + 31619683 = 31619754
107 + 31619647 = 31619754
137 + 31619617 = 31619754
151 + 31619603 = 31619754

Showing the first eight; more decompositions exist.
