Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704212, here are decompositions:
- 19 + 8704193 = 8704212
- 29 + 8704183 = 8704212
- 43 + 8704169 = 8704212
- 53 + 8704159 = 8704212
- 89 + 8704123 = 8704212
- 163 + 8704049 = 8704212
- 241 + 8703971 = 8704212
- 269 + 8703943 = 8704212
Showing the first eight; more decompositions exist.
