Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613442, here are decompositions:

3 + 8613439 = 8613442
113 + 8613329 = 8613442
281 + 8613161 = 8613442
293 + 8613149 = 8613442
353 + 8613089 = 8613442
401 + 8613041 = 8613442
569 + 8612873 = 8613442
641 + 8612801 = 8613442

Showing the first eight; more decompositions exist.
