Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539814, here are decompositions:

101 + 31539713 = 31539814
107 + 31539707 = 31539814
227 + 31539587 = 31539814
347 + 31539467 = 31539814
401 + 31539413 = 31539814
461 + 31539353 = 31539814
827 + 31538987 = 31539814
863 + 31538951 = 31539814

Showing the first eight; more decompositions exist.
