Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724292, here are decompositions:

23 + 8724269 = 8724292
29 + 8724263 = 8724292
131 + 8724161 = 8724292
149 + 8724143 = 8724292
191 + 8724101 = 8724292
359 + 8723933 = 8724292
383 + 8723909 = 8724292
389 + 8723903 = 8724292

Showing the first eight; more decompositions exist.
