Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044, here are decompositions:
- 5 + 1039 = 1044
- 11 + 1033 = 1044
- 13 + 1031 = 1044
- 23 + 1021 = 1044
- 31 + 1013 = 1044
- 47 + 997 = 1044
- 53 + 991 = 1044
- 61 + 983 = 1044
Showing the first eight; more decompositions exist.
