Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476802, here are decompositions:

3 + 31476799 = 31476802
59 + 31476743 = 31476802
179 + 31476623 = 31476802
191 + 31476611 = 31476802
251 + 31476551 = 31476802
293 + 31476509 = 31476802
353 + 31476449 = 31476802
389 + 31476413 = 31476802

Showing the first eight; more decompositions exist.
