Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464748, here are decompositions:

17 + 31464731 = 31464748
47 + 31464701 = 31464748
131 + 31464617 = 31464748
167 + 31464581 = 31464748
191 + 31464557 = 31464748
239 + 31464509 = 31464748
347 + 31464401 = 31464748
389 + 31464359 = 31464748

Showing the first eight; more decompositions exist.
