Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536590, here are decompositions:
- 61 + 31536529 = 31536590
- 109 + 31536481 = 31536590
- 193 + 31536397 = 31536590
- 199 + 31536391 = 31536590
- 229 + 31536361 = 31536590
- 277 + 31536313 = 31536590
- 367 + 31536223 = 31536590
- 541 + 31536049 = 31536590
Showing the first eight; more decompositions exist.
