Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496250, here are decompositions:

29 + 31496221 = 31496250
31 + 31496219 = 31496250
41 + 31496209 = 31496250
89 + 31496161 = 31496250
109 + 31496141 = 31496250
127 + 31496123 = 31496250
131 + 31496119 = 31496250
151 + 31496099 = 31496250

Showing the first eight; more decompositions exist.
