Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547632, here are decompositions:

3 + 31547629 = 31547632
23 + 31547609 = 31547632
41 + 31547591 = 31547632
101 + 31547531 = 31547632
113 + 31547519 = 31547632
173 + 31547459 = 31547632
191 + 31547441 = 31547632
293 + 31547339 = 31547632

Showing the first eight; more decompositions exist.
