Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732442, here are decompositions:

11 + 8732431 = 8732442
13 + 8732429 = 8732442
31 + 8732411 = 8732442
71 + 8732371 = 8732442
73 + 8732369 = 8732442
79 + 8732363 = 8732442
151 + 8732291 = 8732442
181 + 8732261 = 8732442

Showing the first eight; more decompositions exist.
