Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539094, here are decompositions:

5 + 31539089 = 31539094
11 + 31539083 = 31539094
47 + 31539047 = 31539094
107 + 31538987 = 31539094
383 + 31538711 = 31539094
401 + 31538693 = 31539094
617 + 31538477 = 31539094
683 + 31538411 = 31539094

Showing the first eight; more decompositions exist.
