Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752442, here are decompositions:

103 + 8752339 = 8752442
151 + 8752291 = 8752442
211 + 8752231 = 8752442
241 + 8752201 = 8752442
313 + 8752129 = 8752442
379 + 8752063 = 8752442
409 + 8752033 = 8752442
571 + 8751871 = 8752442

Showing the first eight; more decompositions exist.
