Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732242, here are decompositions:

3 + 8732239 = 8732242
41 + 8732201 = 8732242
53 + 8732189 = 8732242
83 + 8732159 = 8732242
149 + 8732093 = 8732242
191 + 8732051 = 8732242
251 + 8731991 = 8732242
263 + 8731979 = 8732242

Showing the first eight; more decompositions exist.
