Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450348, here are decompositions:

101 + 31450247 = 31450348
131 + 31450217 = 31450348
317 + 31450031 = 31450348
359 + 31449989 = 31450348
557 + 31449791 = 31450348
647 + 31449701 = 31450348
659 + 31449689 = 31450348
701 + 31449647 = 31450348

Showing the first eight; more decompositions exist.
