Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724442, here are decompositions:

5 + 8724437 = 8724442
71 + 8724371 = 8724442
113 + 8724329 = 8724442
131 + 8724311 = 8724442
149 + 8724293 = 8724442
173 + 8724269 = 8724442
179 + 8724263 = 8724442
281 + 8724161 = 8724442

Showing the first eight; more decompositions exist.
