Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742450, here are decompositions:

29 + 8742421 = 8742450
71 + 8742379 = 8742450
83 + 8742367 = 8742450
97 + 8742353 = 8742450
103 + 8742347 = 8742450
137 + 8742313 = 8742450
191 + 8742259 = 8742450
257 + 8742193 = 8742450

Showing the first eight; more decompositions exist.
