Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472374, here are decompositions:

23 + 31472351 = 31472374
83 + 31472291 = 31472374
113 + 31472261 = 31472374
173 + 31472201 = 31472374
191 + 31472183 = 31472374
251 + 31472123 = 31472374
383 + 31471991 = 31472374
467 + 31471907 = 31472374

Showing the first eight; more decompositions exist.
