Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642452, here are decompositions:

3 + 8642449 = 8642452
23 + 8642429 = 8642452
149 + 8642303 = 8642452
263 + 8642189 = 8642452
293 + 8642159 = 8642452
311 + 8642141 = 8642452
353 + 8642099 = 8642452
389 + 8642063 = 8642452

Showing the first eight; more decompositions exist.
