Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539254, here are decompositions:

13 + 31539241 = 31539254
181 + 31539073 = 31539254
193 + 31539061 = 31539254
211 + 31539043 = 31539254
367 + 31538887 = 31539254
541 + 31538713 = 31539254
601 + 31538653 = 31539254
613 + 31538641 = 31539254

Showing the first eight; more decompositions exist.
