Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544094, here are decompositions:

5 + 31544089 = 31544094
17 + 31544077 = 31544094
37 + 31544057 = 31544094
41 + 31544053 = 31544094
53 + 31544041 = 31544094
61 + 31544033 = 31544094
73 + 31544021 = 31544094
83 + 31544011 = 31544094

Showing the first eight; more decompositions exist.
