Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573268, here are decompositions:

7 + 31573261 = 31573268
79 + 31573189 = 31573268
157 + 31573111 = 31573268
211 + 31573057 = 31573268
241 + 31573027 = 31573268
367 + 31572901 = 31573268
499 + 31572769 = 31573268
541 + 31572727 = 31573268

Showing the first eight; more decompositions exist.
