Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994640, here are decompositions:
- 19 + 994621 = 994640
- 37 + 994603 = 994640
- 61 + 994579 = 994640
- 79 + 994561 = 994640
- 139 + 994501 = 994640
- 151 + 994489 = 994640
- 193 + 994447 = 994640
- 223 + 994417 = 994640
Showing the first eight; more decompositions exist.
