Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573254, here are decompositions:

43 + 31573211 = 31573254
101 + 31573153 = 31573254
103 + 31573151 = 31573254
127 + 31573127 = 31573254
131 + 31573123 = 31573254
151 + 31573103 = 31573254
197 + 31573057 = 31573254
227 + 31573027 = 31573254

Showing the first eight; more decompositions exist.
