Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742994, here are decompositions:

17 + 8742977 = 8742994
53 + 8742941 = 8742994
107 + 8742887 = 8742994
137 + 8742857 = 8742994
173 + 8742821 = 8742994
317 + 8742677 = 8742994
443 + 8742551 = 8742994
593 + 8742401 = 8742994

Showing the first eight; more decompositions exist.
