Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732538, here are decompositions:

37 + 8732501 = 8732538
107 + 8732431 = 8732538
109 + 8732429 = 8732538
127 + 8732411 = 8732538
167 + 8732371 = 8732538
229 + 8732309 = 8732538
239 + 8732299 = 8732538
277 + 8732261 = 8732538

Showing the first eight; more decompositions exist.
