Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49280, here are decompositions:
- 3 + 49277 = 49280
- 19 + 49261 = 49280
- 73 + 49207 = 49280
- 79 + 49201 = 49280
- 103 + 49177 = 49280
- 109 + 49171 = 49280
- 157 + 49123 = 49280
- 163 + 49117 = 49280
Showing the first eight; more decompositions exist.
