Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538962, here are decompositions:

11 + 31538951 = 31538962
173 + 31538789 = 31538962
233 + 31538729 = 31538962
251 + 31538711 = 31538962
269 + 31538693 = 31538962
383 + 31538579 = 31538962
401 + 31538561 = 31538962
701 + 31538261 = 31538962

Showing the first eight; more decompositions exist.
