Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986238, here are decompositions:
- 31 + 986207 = 986238
- 41 + 986197 = 986238
- 47 + 986191 = 986238
- 61 + 986177 = 986238
- 89 + 986149 = 986238
- 101 + 986137 = 986238
- 107 + 986131 = 986238
- 137 + 986101 = 986238
Showing the first eight; more decompositions exist.
