Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594854, here are decompositions:

41 + 31594813 = 31594854
43 + 31594811 = 31594854
47 + 31594807 = 31594854
97 + 31594757 = 31594854
107 + 31594747 = 31594854
127 + 31594727 = 31594854
163 + 31594691 = 31594854
173 + 31594681 = 31594854

Showing the first eight; more decompositions exist.
