Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535292, here are decompositions:
- 29 + 31535263 = 31535292
- 59 + 31535233 = 31535292
- 73 + 31535219 = 31535292
- 79 + 31535213 = 31535292
- 109 + 31535183 = 31535292
- 149 + 31535143 = 31535292
- 179 + 31535113 = 31535292
- 211 + 31535081 = 31535292
Showing the first eight; more decompositions exist.
