Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474326, here are decompositions:

7 + 31474319 = 31474326
19 + 31474307 = 31474326
73 + 31474253 = 31474326
109 + 31474217 = 31474326
113 + 31474213 = 31474326
197 + 31474129 = 31474326
269 + 31474057 = 31474326
283 + 31474043 = 31474326

Showing the first eight; more decompositions exist.
