Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535684, here are decompositions:
- 3 + 31535681 = 31535684
- 13 + 31535671 = 31535684
- 181 + 31535503 = 31535684
- 307 + 31535377 = 31535684
- 373 + 31535311 = 31535684
- 421 + 31535263 = 31535684
- 457 + 31535227 = 31535684
- 541 + 31535143 = 31535684
Showing the first eight; more decompositions exist.
