Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945650, here are decompositions:

3 + 945647 = 945650
19 + 945631 = 945650
61 + 945589 = 945650
73 + 945577 = 945650
103 + 945547 = 945650
193 + 945457 = 945650
241 + 945409 = 945650
283 + 945367 = 945650

Showing the first eight; more decompositions exist.
