Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540536, here are decompositions:
- 7 + 31540529 = 31540536
- 37 + 31540499 = 31540536
- 43 + 31540493 = 31540536
- 47 + 31540489 = 31540536
- 173 + 31540363 = 31540536
- 193 + 31540343 = 31540536
- 197 + 31540339 = 31540536
- 227 + 31540309 = 31540536
Showing the first eight; more decompositions exist.
