Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742300, here are decompositions:
- 37 + 8742263 = 8742300
- 41 + 8742259 = 8742300
- 103 + 8742197 = 8742300
- 107 + 8742193 = 8742300
- 113 + 8742187 = 8742300
- 131 + 8742169 = 8742300
- 139 + 8742161 = 8742300
- 167 + 8742133 = 8742300
Showing the first eight; more decompositions exist.
