Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961972, here are decompositions:

29 + 961943 = 961972
101 + 961871 = 961972
131 + 961841 = 961972
233 + 961739 = 961972
239 + 961733 = 961972
269 + 961703 = 961972
281 + 961691 = 961972
293 + 961679 = 961972

Showing the first eight; more decompositions exist.
