Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472262, here are decompositions:

23 + 31472239 = 31472262
53 + 31472209 = 31472262
61 + 31472201 = 31472262
71 + 31472191 = 31472262
79 + 31472183 = 31472262
83 + 31472179 = 31472262
103 + 31472159 = 31472262
109 + 31472153 = 31472262

Showing the first eight; more decompositions exist.
