Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593876, here are decompositions:

7 + 31593869 = 31593876
37 + 31593839 = 31593876
43 + 31593833 = 31593876
79 + 31593797 = 31593876
89 + 31593787 = 31593876
109 + 31593767 = 31593876
113 + 31593763 = 31593876
157 + 31593719 = 31593876

Showing the first eight; more decompositions exist.
