Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534482, here are decompositions:
- 41 + 31534441 = 31534482
- 53 + 31534429 = 31534482
- 59 + 31534423 = 31534482
- 71 + 31534411 = 31534482
- 113 + 31534369 = 31534482
- 139 + 31534343 = 31534482
- 149 + 31534333 = 31534482
- 181 + 31534301 = 31534482
Showing the first eight; more decompositions exist.
