Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547814, here are decompositions:

31 + 31547783 = 31547814
83 + 31547731 = 31547814
107 + 31547707 = 31547814
113 + 31547701 = 31547814
131 + 31547683 = 31547814
173 + 31547641 = 31547814
197 + 31547617 = 31547814
223 + 31547591 = 31547814

Showing the first eight; more decompositions exist.
