Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535364, here are decompositions:
- 23 + 31535341 = 31535364
- 37 + 31535327 = 31535364
- 43 + 31535321 = 31535364
- 53 + 31535311 = 31535364
- 101 + 31535263 = 31535364
- 131 + 31535233 = 31535364
- 137 + 31535227 = 31535364
- 151 + 31535213 = 31535364
Showing the first eight; more decompositions exist.
