Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595654, here are decompositions:

43 + 31595611 = 31595654
61 + 31595593 = 31595654
73 + 31595581 = 31595654
271 + 31595383 = 31595654
283 + 31595371 = 31595654
691 + 31594963 = 31595654
751 + 31594903 = 31595654
787 + 31594867 = 31595654

Showing the first eight; more decompositions exist.
