Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977990, here are decompositions:

19 + 977971 = 977990
67 + 977923 = 977990
109 + 977881 = 977990
199 + 977791 = 977990
229 + 977761 = 977990
271 + 977719 = 977990
379 + 977611 = 977990
397 + 977593 = 977990

Showing the first eight; more decompositions exist.
