Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977812, here are decompositions:

89 + 977723 = 977812
131 + 977681 = 977812
401 + 977411 = 977812
443 + 977369 = 977812
449 + 977363 = 977812
461 + 977351 = 977812
569 + 977243 = 977812
743 + 977069 = 977812

Showing the first eight; more decompositions exist.
