Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517060, here are decompositions:

67 + 31516993 = 31517060
79 + 31516981 = 31517060
109 + 31516951 = 31517060
181 + 31516879 = 31517060
241 + 31516819 = 31517060
271 + 31516789 = 31517060
283 + 31516777 = 31517060
307 + 31516753 = 31517060

Showing the first eight; more decompositions exist.
