Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724070, here are decompositions:

83 + 8723987 = 8724070
137 + 8723933 = 8724070
149 + 8723921 = 8724070
167 + 8723903 = 8724070
191 + 8723879 = 8724070
263 + 8723807 = 8724070
281 + 8723789 = 8724070
431 + 8723639 = 8724070

Showing the first eight; more decompositions exist.
