Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972838, here are decompositions:

5 + 972833 = 972838
11 + 972827 = 972838
137 + 972701 = 972838
227 + 972611 = 972838
239 + 972599 = 972838
257 + 972581 = 972838
281 + 972557 = 972838
431 + 972407 = 972838

Showing the first eight; more decompositions exist.
