Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595042, here are decompositions:

43 + 31594999 = 31595042
79 + 31594963 = 31595042
139 + 31594903 = 31595042
181 + 31594861 = 31595042
229 + 31594813 = 31595042
313 + 31594729 = 31595042
433 + 31594609 = 31595042
463 + 31594579 = 31595042

Showing the first eight; more decompositions exist.
