Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593290, here are decompositions:

37 + 31593253 = 31593290
97 + 31593193 = 31593290
181 + 31593109 = 31593290
193 + 31593097 = 31593290
307 + 31592983 = 31593290
331 + 31592959 = 31593290
367 + 31592923 = 31593290
457 + 31592833 = 31593290

Showing the first eight; more decompositions exist.
