Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031972, here are decompositions:

61 + 1031911 = 1031972
103 + 1031869 = 1031972
163 + 1031809 = 1031972
211 + 1031761 = 1031972
241 + 1031731 = 1031972
349 + 1031623 = 1031972
379 + 1031593 = 1031972
439 + 1031533 = 1031972

Showing the first eight; more decompositions exist.
