Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597850, here are decompositions:

7 + 31597843 = 31597850
73 + 31597777 = 31597850
157 + 31597693 = 31597850
199 + 31597651 = 31597850
211 + 31597639 = 31597850
367 + 31597483 = 31597850
379 + 31597471 = 31597850
397 + 31597453 = 31597850

Showing the first eight; more decompositions exist.
