Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977642, here are decompositions:

13 + 977629 = 977642
31 + 977611 = 977642
103 + 977539 = 977642
229 + 977413 = 977642
283 + 977359 = 977642
373 + 977269 = 977642
409 + 977233 = 977642
433 + 977209 = 977642

Showing the first eight; more decompositions exist.
