Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472938, here are decompositions:

17 + 472921 = 472938
29 + 472909 = 472938
31 + 472907 = 472938
79 + 472859 = 472938
101 + 472837 = 472938
107 + 472831 = 472938
139 + 472799 = 472938
197 + 472741 = 472938

Showing the first eight; more decompositions exist.
