Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986440, here are decompositions:
- 3 + 986437 = 986440
- 11 + 986429 = 986440
- 23 + 986417 = 986440
- 29 + 986411 = 986440
- 71 + 986369 = 986440
- 89 + 986351 = 986440
- 101 + 986339 = 986440
- 107 + 986333 = 986440
Showing the first eight; more decompositions exist.
