Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472274, here are decompositions:

13 + 31472261 = 31472274
73 + 31472201 = 31472274
83 + 31472191 = 31472274
107 + 31472167 = 31472274
131 + 31472143 = 31472274
151 + 31472123 = 31472274
167 + 31472107 = 31472274
233 + 31472041 = 31472274

Showing the first eight; more decompositions exist.
