Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030, here are decompositions:
- 11 + 1019 = 1030
- 17 + 1013 = 1030
- 47 + 983 = 1030
- 53 + 977 = 1030
- 59 + 971 = 1030
- 83 + 947 = 1030
- 89 + 941 = 1030
- 101 + 929 = 1030
Showing the first eight; more decompositions exist.
