Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977144, here are decompositions:

37 + 977107 = 977144
97 + 977047 = 977144
193 + 976951 = 977144
211 + 976933 = 977144
367 + 976777 = 977144
523 + 976621 = 977144
607 + 976537 = 977144
631 + 976513 = 977144

Showing the first eight; more decompositions exist.
