Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943690, here are decompositions:

53 + 943637 = 943690
89 + 943601 = 943690
101 + 943589 = 943690
149 + 943541 = 943690
179 + 943511 = 943690
191 + 943499 = 943690
269 + 943421 = 943690
281 + 943409 = 943690

Showing the first eight; more decompositions exist.
