Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742372, here are decompositions:

5 + 8742367 = 8742372
13 + 8742359 = 8742372
19 + 8742353 = 8742372
59 + 8742313 = 8742372
109 + 8742263 = 8742372
113 + 8742259 = 8742372
179 + 8742193 = 8742372
211 + 8742161 = 8742372

Showing the first eight; more decompositions exist.
