Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27974, here are decompositions:
- 7 + 27967 = 27974
- 13 + 27961 = 27974
- 31 + 27943 = 27974
- 73 + 27901 = 27974
- 127 + 27847 = 27974
- 151 + 27823 = 27974
- 157 + 27817 = 27974
- 181 + 27793 = 27974
Showing the first eight; more decompositions exist.
