Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732380, here are decompositions:

11 + 8732369 = 8732380
17 + 8732363 = 8732380
29 + 8732351 = 8732380
71 + 8732309 = 8732380
89 + 8732291 = 8732380
179 + 8732201 = 8732380
191 + 8732189 = 8732380
257 + 8732123 = 8732380

Showing the first eight; more decompositions exist.
