Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472368, here are decompositions:

17 + 31472351 = 31472368
29 + 31472339 = 31472368
107 + 31472261 = 31472368
167 + 31472201 = 31472368
401 + 31471967 = 31472368
461 + 31471907 = 31472368
467 + 31471901 = 31472368
569 + 31471799 = 31472368

Showing the first eight; more decompositions exist.
