Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732158, here are decompositions:

41 + 8732117 = 8732158
107 + 8732051 = 8732158
131 + 8732027 = 8732158
167 + 8731991 = 8732158
179 + 8731979 = 8732158
251 + 8731907 = 8732158
257 + 8731901 = 8732158
401 + 8731757 = 8732158

Showing the first eight; more decompositions exist.
