Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977388, here are decompositions:

19 + 977369 = 977388
29 + 977359 = 977388
31 + 977357 = 977388
37 + 977351 = 977388
89 + 977299 = 977388
131 + 977257 = 977388
149 + 977239 = 977388
179 + 977209 = 977388

Showing the first eight; more decompositions exist.
