Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535360, here are decompositions:
- 19 + 31535341 = 31535360
- 97 + 31535263 = 31535360
- 127 + 31535233 = 31535360
- 229 + 31535131 = 31535360
- 277 + 31535083 = 31535360
- 349 + 31535011 = 31535360
- 379 + 31534981 = 31535360
- 487 + 31534873 = 31535360
Showing the first eight; more decompositions exist.
