Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51542, here are decompositions:
- 3 + 51539 = 51542
- 31 + 51511 = 51542
- 61 + 51481 = 51542
- 103 + 51439 = 51542
- 181 + 51361 = 51542
- 193 + 51349 = 51542
- 199 + 51343 = 51542
- 313 + 51229 = 51542
Showing the first eight; more decompositions exist.
