Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535040, here are decompositions:
- 7 + 31535033 = 31535040
- 29 + 31535011 = 31535040
- 41 + 31534999 = 31535040
- 59 + 31534981 = 31535040
- 79 + 31534961 = 31535040
- 127 + 31534913 = 31535040
- 167 + 31534873 = 31535040
- 239 + 31534801 = 31535040
Showing the first eight; more decompositions exist.
