Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482670, here are decompositions:

3 + 31482667 = 31482670
29 + 31482641 = 31482670
53 + 31482617 = 31482670
71 + 31482599 = 31482670
83 + 31482587 = 31482670
101 + 31482569 = 31482670
269 + 31482401 = 31482670
281 + 31482389 = 31482670

Showing the first eight; more decompositions exist.
