Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8972, here are decompositions:
- 3 + 8969 = 8972
- 31 + 8941 = 8972
- 43 + 8929 = 8972
- 79 + 8893 = 8972
- 109 + 8863 = 8972
- 151 + 8821 = 8972
- 193 + 8779 = 8972
- 211 + 8761 = 8972
Showing the first eight; more decompositions exist.
