Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452900, here are decompositions:

41 + 31452859 = 31452900
71 + 31452829 = 31452900
97 + 31452803 = 31452900
107 + 31452793 = 31452900
131 + 31452769 = 31452900
137 + 31452763 = 31452900
151 + 31452749 = 31452900
173 + 31452727 = 31452900

Showing the first eight; more decompositions exist.
