Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004, here are decompositions:
- 7 + 997 = 1004
- 13 + 991 = 1004
- 37 + 967 = 1004
- 67 + 937 = 1004
- 97 + 907 = 1004
- 127 + 877 = 1004
- 151 + 853 = 1004
- 181 + 823 = 1004
Showing the first eight; more decompositions exist.
