Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738912, here are decompositions:

31 + 8738881 = 8738912
73 + 8738839 = 8738912
103 + 8738809 = 8738912
199 + 8738713 = 8738912
241 + 8738671 = 8738912
271 + 8738641 = 8738912
331 + 8738581 = 8738912
373 + 8738539 = 8738912

Showing the first eight; more decompositions exist.
