Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15290, here are decompositions:
- 3 + 15287 = 15290
- 13 + 15277 = 15290
- 19 + 15271 = 15290
- 31 + 15259 = 15290
- 73 + 15217 = 15290
- 97 + 15193 = 15290
- 103 + 15187 = 15290
- 151 + 15139 = 15290
Showing the first eight; more decompositions exist.
