Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452700, here are decompositions:

17 + 31452683 = 31452700
23 + 31452677 = 31452700
101 + 31452599 = 31452700
113 + 31452587 = 31452700
173 + 31452527 = 31452700
179 + 31452521 = 31452700
239 + 31452461 = 31452700
281 + 31452419 = 31452700

Showing the first eight; more decompositions exist.
