Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988972, here are decompositions:
- 71 + 988901 = 988972
- 113 + 988859 = 988972
- 239 + 988733 = 988972
- 311 + 988661 = 988972
- 389 + 988583 = 988972
- 401 + 988571 = 988972
- 431 + 988541 = 988972
- 461 + 988511 = 988972
Showing the first eight; more decompositions exist.
