Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544100, here are decompositions:

11 + 31544089 = 31544100
23 + 31544077 = 31544100
43 + 31544057 = 31544100
47 + 31544053 = 31544100
59 + 31544041 = 31544100
61 + 31544039 = 31544100
67 + 31544033 = 31544100
79 + 31544021 = 31544100

Showing the first eight; more decompositions exist.
