Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534452, here are decompositions:
- 11 + 31534441 = 31534452
- 23 + 31534429 = 31534452
- 29 + 31534423 = 31534452
- 41 + 31534411 = 31534452
- 83 + 31534369 = 31534452
- 109 + 31534343 = 31534452
- 151 + 31534301 = 31534452
- 181 + 31534271 = 31534452
Showing the first eight; more decompositions exist.
