Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472358, here are decompositions:

7 + 31472351 = 31472358
19 + 31472339 = 31472358
67 + 31472291 = 31472358
97 + 31472261 = 31472358
149 + 31472209 = 31472358
157 + 31472201 = 31472358
167 + 31472191 = 31472358
179 + 31472179 = 31472358

Showing the first eight; more decompositions exist.
