Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472204, here are decompositions:

3 + 31472201 = 31472204
13 + 31472191 = 31472204
37 + 31472167 = 31472204
61 + 31472143 = 31472204
73 + 31472131 = 31472204
97 + 31472107 = 31472204
151 + 31472053 = 31472204
163 + 31472041 = 31472204

Showing the first eight; more decompositions exist.
