Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961772, here are decompositions:

3 + 961769 = 961772
43 + 961729 = 961772
109 + 961663 = 961772
139 + 961633 = 961772
223 + 961549 = 961772
241 + 961531 = 961772
313 + 961459 = 961772
373 + 961399 = 961772

Showing the first eight; more decompositions exist.
