Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577778, here are decompositions:

139 + 577639 = 577778
151 + 577627 = 577778
241 + 577537 = 577778
307 + 577471 = 577778
379 + 577399 = 577778
499 + 577279 = 577778
601 + 577177 = 577778
631 + 577147 = 577778

Showing the first eight; more decompositions exist.
