Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990360, here are decompositions:
- 11 + 990349 = 990360
- 29 + 990331 = 990360
- 31 + 990329 = 990360
- 37 + 990323 = 990360
- 47 + 990313 = 990360
- 53 + 990307 = 990360
- 67 + 990293 = 990360
- 71 + 990289 = 990360
Showing the first eight; more decompositions exist.
