Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501234, here are decompositions:

3 + 31501231 = 31501234
5 + 31501229 = 31501234
173 + 31501061 = 31501234
197 + 31501037 = 31501234
257 + 31500977 = 31501234
293 + 31500941 = 31501234
311 + 31500923 = 31501234
461 + 31500773 = 31501234

Showing the first eight; more decompositions exist.
