Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482652, here are decompositions:

11 + 31482641 = 31482652
53 + 31482599 = 31482652
83 + 31482569 = 31482652
101 + 31482551 = 31482652
251 + 31482401 = 31482652
263 + 31482389 = 31482652
359 + 31482293 = 31482652
479 + 31482173 = 31482652

Showing the first eight; more decompositions exist.
