Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476562, here are decompositions:

11 + 31476551 = 31476562
53 + 31476509 = 31476562
101 + 31476461 = 31476562
113 + 31476449 = 31476562
149 + 31476413 = 31476562
179 + 31476383 = 31476562
191 + 31476371 = 31476562
311 + 31476251 = 31476562

Showing the first eight; more decompositions exist.
