Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74872, here are decompositions:

3 + 74869 = 74872
11 + 74861 = 74872
29 + 74843 = 74872
41 + 74831 = 74872
101 + 74771 = 74872
113 + 74759 = 74872
173 + 74699 = 74872
263 + 74609 = 74872

Showing the first eight; more decompositions exist.
