Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478482, here are decompositions:

3 + 31478479 = 31478482
11 + 31478471 = 31478482
53 + 31478429 = 31478482
71 + 31478411 = 31478482
83 + 31478399 = 31478482
89 + 31478393 = 31478482
131 + 31478351 = 31478482
149 + 31478333 = 31478482

Showing the first eight; more decompositions exist.
