Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595126, here are decompositions:

67 + 31595059 = 31595126
127 + 31594999 = 31595126
139 + 31594987 = 31595126
163 + 31594963 = 31595126
223 + 31594903 = 31595126
313 + 31594813 = 31595126
379 + 31594747 = 31595126
397 + 31594729 = 31595126

Showing the first eight; more decompositions exist.
