Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595338, here are decompositions:

59 + 31595279 = 31595338
101 + 31595237 = 31595338
149 + 31595189 = 31595338
197 + 31595141 = 31595338
317 + 31595021 = 31595338
347 + 31594991 = 31595338
419 + 31594919 = 31595338
431 + 31594907 = 31595338

Showing the first eight; more decompositions exist.
