Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594994, here are decompositions:

3 + 31594991 = 31594994
7 + 31594987 = 31594994
31 + 31594963 = 31594994
127 + 31594867 = 31594994
181 + 31594813 = 31594994
313 + 31594681 = 31594994
367 + 31594627 = 31594994
397 + 31594597 = 31594994

Showing the first eight; more decompositions exist.
