Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474852, here are decompositions:

23 + 31474829 = 31474852
89 + 31474763 = 31474852
131 + 31474721 = 31474852
179 + 31474673 = 31474852
251 + 31474601 = 31474852
281 + 31474571 = 31474852
293 + 31474559 = 31474852
419 + 31474433 = 31474852

Showing the first eight; more decompositions exist.
