Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747242, here are decompositions:

29 + 8747213 = 8747242
71 + 8747171 = 8747242
83 + 8747159 = 8747242
131 + 8747111 = 8747242
149 + 8747093 = 8747242
263 + 8746979 = 8747242
293 + 8746949 = 8747242
431 + 8746811 = 8747242

Showing the first eight; more decompositions exist.
