Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019972, here are decompositions:

73 + 1019899 = 1019972
241 + 1019731 = 1019972
271 + 1019701 = 1019972
409 + 1019563 = 1019972
439 + 1019533 = 1019972
463 + 1019509 = 1019972
523 + 1019449 = 1019972
619 + 1019353 = 1019972

Showing the first eight; more decompositions exist.
