Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595754, here are decompositions:

23 + 31595731 = 31595754
31 + 31595723 = 31595754
37 + 31595717 = 31595754
53 + 31595701 = 31595754
67 + 31595687 = 31595754
83 + 31595671 = 31595754
97 + 31595657 = 31595754
101 + 31595653 = 31595754

Showing the first eight; more decompositions exist.
