Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472232, here are decompositions:

23 + 31472209 = 31472232
31 + 31472201 = 31472232
41 + 31472191 = 31472232
53 + 31472179 = 31472232
73 + 31472159 = 31472232
79 + 31472153 = 31472232
83 + 31472149 = 31472232
89 + 31472143 = 31472232

Showing the first eight; more decompositions exist.
