Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593086, here are decompositions:

103 + 31592983 = 31593086
127 + 31592959 = 31593086
139 + 31592947 = 31593086
163 + 31592923 = 31593086
277 + 31592809 = 31593086
307 + 31592779 = 31593086
313 + 31592773 = 31593086
409 + 31592677 = 31593086

Showing the first eight; more decompositions exist.
