Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15488, here are decompositions:
- 37 + 15451 = 15488
- 61 + 15427 = 15488
- 97 + 15391 = 15488
- 127 + 15361 = 15488
- 139 + 15349 = 15488
- 157 + 15331 = 15488
- 181 + 15307 = 15488
- 199 + 15289 = 15488
Showing the first eight; more decompositions exist.
