Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51530, here are decompositions:
- 13 + 51517 = 51530
- 19 + 51511 = 51530
- 43 + 51487 = 51530
- 103 + 51427 = 51530
- 109 + 51421 = 51530
- 181 + 51349 = 51530
- 223 + 51307 = 51530
- 313 + 51217 = 51530
Showing the first eight; more decompositions exist.
