Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541862, here are decompositions:
- 5 + 31541857 = 31541862
- 101 + 31541761 = 31541862
- 211 + 31541651 = 31541862
- 229 + 31541633 = 31541862
- 251 + 31541611 = 31541862
- 271 + 31541591 = 31541862
- 281 + 31541581 = 31541862
- 293 + 31541569 = 31541862
Showing the first eight; more decompositions exist.
