Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516022, here are decompositions:

73 + 31515949 = 31516022
103 + 31515919 = 31516022
463 + 31515559 = 31516022
739 + 31515283 = 31516022
751 + 31515271 = 31516022
829 + 31515193 = 31516022
1129 + 31514893 = 31516022
1153 + 31514869 = 31516022

Showing the first eight; more decompositions exist.
