Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30974, here are decompositions:
- 3 + 30971 = 30974
- 37 + 30937 = 30974
- 43 + 30931 = 30974
- 103 + 30871 = 30974
- 157 + 30817 = 30974
- 193 + 30781 = 30974
- 211 + 30763 = 30974
- 271 + 30703 = 30974
Showing the first eight; more decompositions exist.
