Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977972, here are decompositions:

181 + 977791 = 977972
211 + 977761 = 977972
379 + 977593 = 977972
433 + 977539 = 977972
613 + 977359 = 977972
673 + 977299 = 977972
733 + 977239 = 977972
739 + 977233 = 977972

Showing the first eight; more decompositions exist.
