Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720744, here are decompositions:

31 + 8720713 = 8720744
37 + 8720707 = 8720744
73 + 8720671 = 8720744
127 + 8720617 = 8720744
163 + 8720581 = 8720744
211 + 8720533 = 8720744
313 + 8720431 = 8720744
337 + 8720407 = 8720744

Showing the first eight; more decompositions exist.
