Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998280, here are decompositions:
- 7 + 998273 = 998280
- 37 + 998243 = 998280
- 43 + 998237 = 998280
- 61 + 998219 = 998280
- 67 + 998213 = 998280
- 79 + 998201 = 998280
- 83 + 998197 = 998280
- 113 + 998167 = 998280
Showing the first eight; more decompositions exist.
