Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988040, here are decompositions:
- 7 + 988033 = 988040
- 19 + 988021 = 988040
- 43 + 987997 = 988040
- 61 + 987979 = 988040
- 127 + 987913 = 988040
- 409 + 987631 = 988040
- 433 + 987607 = 988040
- 499 + 987541 = 988040
Showing the first eight; more decompositions exist.
