Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517030, here are decompositions:

3 + 31517027 = 31517030
19 + 31517011 = 31517030
37 + 31516993 = 31517030
79 + 31516951 = 31517030
151 + 31516879 = 31517030
211 + 31516819 = 31517030
241 + 31516789 = 31517030
277 + 31516753 = 31517030

Showing the first eight; more decompositions exist.
