Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708238, here are decompositions:
- 37 + 8708201 = 8708238
- 41 + 8708197 = 8708238
- 79 + 8708159 = 8708238
- 109 + 8708129 = 8708238
- 137 + 8708101 = 8708238
- 151 + 8708087 = 8708238
- 157 + 8708081 = 8708238
- 167 + 8708071 = 8708238
Showing the first eight; more decompositions exist.
