Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538972, here are decompositions:

29 + 538943 = 538972
41 + 538931 = 538972
101 + 538871 = 538972
131 + 538841 = 538972
149 + 538823 = 538972
173 + 538799 = 538972
233 + 538739 = 538972
251 + 538721 = 538972

Showing the first eight; more decompositions exist.
