Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585850, here are decompositions:
- 13 + 31585837 = 31585850
- 67 + 31585783 = 31585850
- 73 + 31585777 = 31585850
- 271 + 31585579 = 31585850
- 313 + 31585537 = 31585850
- 349 + 31585501 = 31585850
- 397 + 31585453 = 31585850
- 409 + 31585441 = 31585850
Showing the first eight; more decompositions exist.
