Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045802, here are decompositions:

3 + 1045799 = 1045802
73 + 1045729 = 1045802
139 + 1045663 = 1045802
151 + 1045651 = 1045802
181 + 1045621 = 1045802
229 + 1045573 = 1045802
379 + 1045423 = 1045802
409 + 1045393 = 1045802

Showing the first eight; more decompositions exist.
