Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540586, here are decompositions:
- 13 + 31540573 = 31540586
- 97 + 31540489 = 31540586
- 223 + 31540363 = 31540586
- 277 + 31540309 = 31540586
- 373 + 31540213 = 31540586
- 379 + 31540207 = 31540586
- 397 + 31540189 = 31540586
- 439 + 31540147 = 31540586
Showing the first eight; more decompositions exist.
