Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003972, here are decompositions:

29 + 1003943 = 1003972
41 + 1003931 = 1003972
59 + 1003913 = 1003972
83 + 1003889 = 1003972
131 + 1003841 = 1003972
239 + 1003733 = 1003972
293 + 1003679 = 1003972
353 + 1003619 = 1003972

Showing the first eight; more decompositions exist.
