Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51450, here are decompositions:
- 11 + 51439 = 51450
- 13 + 51437 = 51450
- 19 + 51431 = 51450
- 23 + 51427 = 51450
- 29 + 51421 = 51450
- 31 + 51419 = 51450
- 37 + 51413 = 51450
- 43 + 51407 = 51450
Showing the first eight; more decompositions exist.
