Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961538, here are decompositions:

7 + 961531 = 961538
31 + 961507 = 961538
79 + 961459 = 961538
139 + 961399 = 961538
199 + 961339 = 961538
337 + 961201 = 961538
349 + 961189 = 961538
379 + 961159 = 961538

Showing the first eight; more decompositions exist.
