Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728236, here are decompositions:
- 29 + 8728207 = 8728236
- 43 + 8728193 = 8728236
- 67 + 8728169 = 8728236
- 89 + 8728147 = 8728236
- 107 + 8728129 = 8728236
- 157 + 8728079 = 8728236
- 163 + 8728073 = 8728236
- 199 + 8728037 = 8728236
Showing the first eight; more decompositions exist.
