Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51436, here are decompositions:
- 5 + 51431 = 51436
- 17 + 51419 = 51436
- 23 + 51413 = 51436
- 29 + 51407 = 51436
- 53 + 51383 = 51436
- 89 + 51347 = 51436
- 107 + 51329 = 51436
- 149 + 51287 = 51436
Showing the first eight; more decompositions exist.
