Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544058, here are decompositions:

5 + 31544053 = 31544058
17 + 31544041 = 31544058
19 + 31544039 = 31544058
37 + 31544021 = 31544058
47 + 31544011 = 31544058
61 + 31543997 = 31544058
67 + 31543991 = 31544058
71 + 31543987 = 31544058

Showing the first eight; more decompositions exist.
