Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613490, here are decompositions:

29 + 8613461 = 8613490
167 + 8613323 = 8613490
191 + 8613299 = 8613490
269 + 8613221 = 8613490
383 + 8613107 = 8613490
401 + 8613089 = 8613490
443 + 8613047 = 8613490
449 + 8613041 = 8613490

Showing the first eight; more decompositions exist.
