Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8772, here are decompositions:
- 11 + 8761 = 8772
- 19 + 8753 = 8772
- 31 + 8741 = 8772
- 41 + 8731 = 8772
- 53 + 8719 = 8772
- 59 + 8713 = 8772
- 73 + 8699 = 8772
- 79 + 8693 = 8772
Showing the first eight; more decompositions exist.
