Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732190, here are decompositions:

31 + 8732159 = 8732190
53 + 8732137 = 8732190
67 + 8732123 = 8732190
73 + 8732117 = 8732190
97 + 8732093 = 8732190
109 + 8732081 = 8732190
139 + 8732051 = 8732190
163 + 8732027 = 8732190

Showing the first eight; more decompositions exist.
