Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51830, here are decompositions:
- 3 + 51827 = 51830
- 13 + 51817 = 51830
- 43 + 51787 = 51830
- 61 + 51769 = 51830
- 109 + 51721 = 51830
- 139 + 51691 = 51830
- 151 + 51679 = 51830
- 157 + 51673 = 51830
Showing the first eight; more decompositions exist.
