Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72124, here are decompositions:
- 23 + 72101 = 72124
- 47 + 72077 = 72124
- 71 + 72053 = 72124
- 131 + 71993 = 72124
- 137 + 71987 = 72124
- 191 + 71933 = 72124
- 257 + 71867 = 72124
- 263 + 71861 = 72124
Showing the first eight; more decompositions exist.
