Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594842, here are decompositions:

29 + 31594813 = 31594842
31 + 31594811 = 31594842
43 + 31594799 = 31594842
73 + 31594769 = 31594842
113 + 31594729 = 31594842
151 + 31594691 = 31594842
229 + 31594613 = 31594842
233 + 31594609 = 31594842

Showing the first eight; more decompositions exist.
