Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741778, here are decompositions:

29 + 8741749 = 8741778
37 + 8741741 = 8741778
79 + 8741699 = 8741778
137 + 8741641 = 8741778
139 + 8741639 = 8741778
257 + 8741521 = 8741778
307 + 8741471 = 8741778
347 + 8741431 = 8741778

Showing the first eight; more decompositions exist.
