Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724042, here are decompositions:

29 + 8724013 = 8724042
109 + 8723933 = 8724042
113 + 8723929 = 8724042
139 + 8723903 = 8724042
149 + 8723893 = 8724042
163 + 8723879 = 8724042
191 + 8723851 = 8724042
311 + 8723731 = 8724042

Showing the first eight; more decompositions exist.
