Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724210, here are decompositions:

29 + 8724181 = 8724210
41 + 8724169 = 8724210
67 + 8724143 = 8724210
71 + 8724139 = 8724210
83 + 8724127 = 8724210
109 + 8724101 = 8724210
137 + 8724073 = 8724210
139 + 8724071 = 8724210

Showing the first eight; more decompositions exist.
