Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748890, here are decompositions:

13 + 8748877 = 8748890
37 + 8748853 = 8748890
43 + 8748847 = 8748890
79 + 8748811 = 8748890
103 + 8748787 = 8748890
151 + 8748739 = 8748890
181 + 8748709 = 8748890
307 + 8748583 = 8748890

Showing the first eight; more decompositions exist.
