Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724174, here are decompositions:

5 + 8724169 = 8724174
13 + 8724161 = 8724174
31 + 8724143 = 8724174
47 + 8724127 = 8724174
73 + 8724101 = 8724174
101 + 8724073 = 8724174
103 + 8724071 = 8724174
181 + 8723993 = 8724174

Showing the first eight; more decompositions exist.
