Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594830, here are decompositions:

17 + 31594813 = 31594830
19 + 31594811 = 31594830
23 + 31594807 = 31594830
31 + 31594799 = 31594830
61 + 31594769 = 31594830
73 + 31594757 = 31594830
83 + 31594747 = 31594830
101 + 31594729 = 31594830

Showing the first eight; more decompositions exist.
