Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588904, here are decompositions:
- 7 + 31588897 = 31588904
- 97 + 31588807 = 31588904
- 211 + 31588693 = 31588904
- 421 + 31588483 = 31588904
- 433 + 31588471 = 31588904
- 463 + 31588441 = 31588904
- 547 + 31588357 = 31588904
- 601 + 31588303 = 31588904
Showing the first eight; more decompositions exist.
