Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986220, here are decompositions:
- 7 + 986213 = 986220
- 13 + 986207 = 986220
- 23 + 986197 = 986220
- 29 + 986191 = 986220
- 31 + 986189 = 986220
- 43 + 986177 = 986220
- 71 + 986149 = 986220
- 73 + 986147 = 986220
Showing the first eight; more decompositions exist.
