Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535186, here are decompositions:
- 3 + 31535183 = 31535186
- 13 + 31535173 = 31535186
- 43 + 31535143 = 31535186
- 73 + 31535113 = 31535186
- 79 + 31535107 = 31535186
- 103 + 31535083 = 31535186
- 127 + 31535059 = 31535186
- 307 + 31534879 = 31535186
Showing the first eight; more decompositions exist.
