Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990850, here are decompositions:
- 41 + 990809 = 990850
- 53 + 990797 = 990850
- 83 + 990767 = 990850
- 89 + 990761 = 990850
- 131 + 990719 = 990850
- 251 + 990599 = 990850
- 257 + 990593 = 990850
- 347 + 990503 = 990850
Showing the first eight; more decompositions exist.
