Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994840, here are decompositions:
- 3 + 994837 = 994840
- 23 + 994817 = 994840
- 29 + 994811 = 994840
- 47 + 994793 = 994840
- 71 + 994769 = 994840
- 89 + 994751 = 994840
- 131 + 994709 = 994840
- 149 + 994691 = 994840
Showing the first eight; more decompositions exist.
