Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732406, here are decompositions:

37 + 8732369 = 8732406
43 + 8732363 = 8732406
97 + 8732309 = 8732406
107 + 8732299 = 8732406
149 + 8732257 = 8732406
167 + 8732239 = 8732406
197 + 8732209 = 8732406
269 + 8732137 = 8732406

Showing the first eight; more decompositions exist.
