Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595534, here are decompositions:

67 + 31595467 = 31595534
127 + 31595407 = 31595534
151 + 31595383 = 31595534
163 + 31595371 = 31595534
283 + 31595251 = 31595534
433 + 31595101 = 31595534
547 + 31594987 = 31595534
571 + 31594963 = 31595534

Showing the first eight; more decompositions exist.
