Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535166, here are decompositions:
- 23 + 31535143 = 31535166
- 43 + 31535123 = 31535166
- 53 + 31535113 = 31535166
- 59 + 31535107 = 31535166
- 83 + 31535083 = 31535166
- 107 + 31535059 = 31535166
- 109 + 31535057 = 31535166
- 167 + 31534999 = 31535166
Showing the first eight; more decompositions exist.
