Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51120, here are decompositions:
- 11 + 51109 = 51120
- 59 + 51061 = 51120
- 61 + 51059 = 51120
- 73 + 51047 = 51120
- 89 + 51031 = 51120
- 127 + 50993 = 51120
- 131 + 50989 = 51120
- 149 + 50971 = 51120
Showing the first eight; more decompositions exist.
