Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535300, here are decompositions:
- 37 + 31535263 = 31535300
- 67 + 31535233 = 31535300
- 73 + 31535227 = 31535300
- 127 + 31535173 = 31535300
- 157 + 31535143 = 31535300
- 193 + 31535107 = 31535300
- 241 + 31535059 = 31535300
- 421 + 31534879 = 31535300
Showing the first eight; more decompositions exist.
