Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738472, here are decompositions:

23 + 8738449 = 8738472
73 + 8738399 = 8738472
89 + 8738383 = 8738472
109 + 8738363 = 8738472
139 + 8738333 = 8738472
173 + 8738299 = 8738472
179 + 8738293 = 8738472
191 + 8738281 = 8738472

Showing the first eight; more decompositions exist.
