Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595768, here are decompositions:

37 + 31595731 = 31595768
67 + 31595701 = 31595768
97 + 31595671 = 31595768
157 + 31595611 = 31595768
199 + 31595569 = 31595768
397 + 31595371 = 31595768
709 + 31595059 = 31595768
769 + 31594999 = 31595768

Showing the first eight; more decompositions exist.
