Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593090, here are decompositions:

43 + 31593047 = 31593090
59 + 31593031 = 31593090
79 + 31593011 = 31593090
97 + 31592993 = 31593090
107 + 31592983 = 31593090
131 + 31592959 = 31593090
167 + 31592923 = 31593090
241 + 31592849 = 31593090

Showing the first eight; more decompositions exist.
