Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472412, here are decompositions:

53 + 31472359 = 31472412
61 + 31472351 = 31472412
73 + 31472339 = 31472412
151 + 31472261 = 31472412
173 + 31472239 = 31472412
211 + 31472201 = 31472412
229 + 31472183 = 31472412
233 + 31472179 = 31472412

Showing the first eight; more decompositions exist.
