Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747232, here are decompositions:
- 19 + 8747213 = 8747232
- 41 + 8747191 = 8747232
- 61 + 8747171 = 8747232
- 73 + 8747159 = 8747232
- 113 + 8747119 = 8747232
- 139 + 8747093 = 8747232
- 149 + 8747083 = 8747232
- 191 + 8747041 = 8747232
Showing the first eight; more decompositions exist.
