Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031990, here are decompositions:

67 + 1031923 = 1031990
79 + 1031911 = 1031990
181 + 1031809 = 1031990
229 + 1031761 = 1031990
283 + 1031707 = 1031990
313 + 1031677 = 1031990
367 + 1031623 = 1031990
397 + 1031593 = 1031990

Showing the first eight; more decompositions exist.
