Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472418, here are decompositions:

59 + 31472359 = 31472418
67 + 31472351 = 31472418
79 + 31472339 = 31472418
127 + 31472291 = 31472418
157 + 31472261 = 31472418
179 + 31472239 = 31472418
227 + 31472191 = 31472418
239 + 31472179 = 31472418

Showing the first eight; more decompositions exist.
