Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043990, here are decompositions:

61 + 1043929 = 1043990
67 + 1043923 = 1043990
151 + 1043839 = 1043990
223 + 1043767 = 1043990
229 + 1043761 = 1043990
307 + 1043683 = 1043990
373 + 1043617 = 1043990
397 + 1043593 = 1043990

Showing the first eight; more decompositions exist.
