Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452852, here are decompositions:

23 + 31452829 = 31452852
59 + 31452793 = 31452852
83 + 31452769 = 31452852
89 + 31452763 = 31452852
103 + 31452749 = 31452852
113 + 31452739 = 31452852
131 + 31452721 = 31452852
229 + 31452623 = 31452852

Showing the first eight; more decompositions exist.
