Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738538, here are decompositions:

5 + 8738533 = 8738538
31 + 8738507 = 8738538
47 + 8738491 = 8738538
89 + 8738449 = 8738538
101 + 8738437 = 8738538
131 + 8738407 = 8738538
139 + 8738399 = 8738538
199 + 8738339 = 8738538

Showing the first eight; more decompositions exist.
