Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732290, here are decompositions:

29 + 8732261 = 8732290
89 + 8732201 = 8732290
101 + 8732189 = 8732290
131 + 8732159 = 8732290
167 + 8732123 = 8732290
173 + 8732117 = 8732290
197 + 8732093 = 8732290
239 + 8732051 = 8732290

Showing the first eight; more decompositions exist.
