Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738938, here are decompositions:

101 + 8738837 = 8738938
137 + 8738801 = 8738938
179 + 8738759 = 8738938
227 + 8738711 = 8738938
347 + 8738591 = 8738938
359 + 8738579 = 8738938
431 + 8738507 = 8738938
491 + 8738447 = 8738938

Showing the first eight; more decompositions exist.
