Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742402, here are decompositions:

23 + 8742379 = 8742402
43 + 8742359 = 8742402
89 + 8742313 = 8742402
139 + 8742263 = 8742402
233 + 8742169 = 8742402
241 + 8742161 = 8742402
269 + 8742133 = 8742402
281 + 8742121 = 8742402

Showing the first eight; more decompositions exist.
