Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713442, here are decompositions:

13 + 8713429 = 8713442
43 + 8713399 = 8713442
79 + 8713363 = 8713442
103 + 8713339 = 8713442
139 + 8713303 = 8713442
151 + 8713291 = 8713442
181 + 8713261 = 8713442
193 + 8713249 = 8713442

Showing the first eight; more decompositions exist.
