Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552738, here are decompositions:

5 + 31552733 = 31552738
11 + 31552727 = 31552738
17 + 31552721 = 31552738
29 + 31552709 = 31552738
149 + 31552589 = 31552738
251 + 31552487 = 31552738
317 + 31552421 = 31552738
467 + 31552271 = 31552738

Showing the first eight; more decompositions exist.
