Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738530, here are decompositions:

23 + 8738507 = 8738530
83 + 8738447 = 8738530
131 + 8738399 = 8738530
167 + 8738363 = 8738530
179 + 8738351 = 8738530
191 + 8738339 = 8738530
197 + 8738333 = 8738530
257 + 8738273 = 8738530

Showing the first eight; more decompositions exist.
