Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532292, here are decompositions:
- 13 + 31532279 = 31532292
- 23 + 31532269 = 31532292
- 31 + 31532261 = 31532292
- 73 + 31532219 = 31532292
- 83 + 31532209 = 31532292
- 89 + 31532203 = 31532292
- 151 + 31532141 = 31532292
- 179 + 31532113 = 31532292
Showing the first eight; more decompositions exist.
