Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977490, here are decompositions:

43 + 977447 = 977490
53 + 977437 = 977490
79 + 977411 = 977490
83 + 977407 = 977490
127 + 977363 = 977490
131 + 977359 = 977490
139 + 977351 = 977490
167 + 977323 = 977490

Showing the first eight; more decompositions exist.
