Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595876, here are decompositions:

3 + 31595873 = 31595876
7 + 31595869 = 31595876
43 + 31595833 = 31595876
157 + 31595719 = 31595876
223 + 31595653 = 31595876
283 + 31595593 = 31595876
307 + 31595569 = 31595876
409 + 31595467 = 31595876

Showing the first eight; more decompositions exist.
