Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15524, here are decompositions:
- 13 + 15511 = 15524
- 31 + 15493 = 15524
- 73 + 15451 = 15524
- 97 + 15427 = 15524
- 151 + 15373 = 15524
- 163 + 15361 = 15524
- 193 + 15331 = 15524
- 211 + 15313 = 15524
Showing the first eight; more decompositions exist.
