Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536486, here are decompositions:
- 5 + 31536481 = 31536486
- 83 + 31536403 = 31536486
- 89 + 31536397 = 31536486
- 103 + 31536383 = 31536486
- 127 + 31536359 = 31536486
- 139 + 31536347 = 31536486
- 173 + 31536313 = 31536486
- 193 + 31536293 = 31536486
Showing the first eight; more decompositions exist.
