Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977138, here are decompositions:

31 + 977107 = 977138
181 + 976957 = 977138
229 + 976909 = 977138
439 + 976699 = 977138
499 + 976639 = 977138
577 + 976561 = 977138
601 + 976537 = 977138
661 + 976477 = 977138

Showing the first eight; more decompositions exist.
