Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990760, here are decompositions:
- 41 + 990719 = 990760
- 53 + 990707 = 990760
- 167 + 990593 = 990760
- 257 + 990503 = 990760
- 263 + 990497 = 990760
- 383 + 990377 = 990760
- 389 + 990371 = 990760
- 401 + 990359 = 990760
Showing the first eight; more decompositions exist.
