Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977278, here are decompositions:

131 + 977147 = 977278
191 + 977087 = 977278
257 + 977021 = 977278
359 + 976919 = 977278
461 + 976817 = 977278
479 + 976799 = 977278
557 + 976721 = 977278
569 + 976709 = 977278

Showing the first eight; more decompositions exist.
