Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595510, here are decompositions:

43 + 31595467 = 31595510
103 + 31595407 = 31595510
127 + 31595383 = 31595510
139 + 31595371 = 31595510
337 + 31595173 = 31595510
409 + 31595101 = 31595510
523 + 31594987 = 31595510
547 + 31594963 = 31595510

Showing the first eight; more decompositions exist.
