Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57072, here are decompositions:
- 13 + 57059 = 57072
- 31 + 57041 = 57072
- 73 + 56999 = 57072
- 79 + 56993 = 57072
- 83 + 56989 = 57072
- 89 + 56983 = 57072
- 109 + 56963 = 57072
- 131 + 56941 = 57072
Showing the first eight; more decompositions exist.
