Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977478, here are decompositions:

31 + 977447 = 977478
41 + 977437 = 977478
67 + 977411 = 977478
71 + 977407 = 977478
109 + 977369 = 977478
127 + 977351 = 977478
179 + 977299 = 977478
239 + 977239 = 977478

Showing the first eight; more decompositions exist.
