Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977942, here are decompositions:

19 + 977923 = 977942
61 + 977881 = 977942
139 + 977803 = 977942
151 + 977791 = 977942
181 + 977761 = 977942
223 + 977719 = 977942
271 + 977671 = 977942
313 + 977629 = 977942

Showing the first eight; more decompositions exist.
