Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595522, here are decompositions:

139 + 31595383 = 31595522
151 + 31595371 = 31595522
271 + 31595251 = 31595522
313 + 31595209 = 31595522
349 + 31595173 = 31595522
421 + 31595101 = 31595522
463 + 31595059 = 31595522
523 + 31594999 = 31595522

Showing the first eight; more decompositions exist.
