Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961442, here are decompositions:

43 + 961399 = 961442
103 + 961339 = 961442
199 + 961243 = 961442
241 + 961201 = 961442
283 + 961159 = 961442
373 + 961069 = 961442
379 + 961063 = 961442
409 + 961033 = 961442

Showing the first eight; more decompositions exist.
