Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972820, here are decompositions:

137 + 972683 = 972820
197 + 972623 = 972820
239 + 972581 = 972820
263 + 972557 = 972820
347 + 972473 = 972820
389 + 972431 = 972820
467 + 972353 = 972820
491 + 972329 = 972820

Showing the first eight; more decompositions exist.
