Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480014, here are decompositions:

53 + 31479961 = 31480014
67 + 31479947 = 31480014
157 + 31479857 = 31480014
193 + 31479821 = 31480014
197 + 31479817 = 31480014
211 + 31479803 = 31480014
257 + 31479757 = 31480014
271 + 31479743 = 31480014

Showing the first eight; more decompositions exist.
