Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12770, here are decompositions:
- 7 + 12763 = 12770
- 13 + 12757 = 12770
- 31 + 12739 = 12770
- 67 + 12703 = 12770
- 73 + 12697 = 12770
- 151 + 12619 = 12770
- 157 + 12613 = 12770
- 181 + 12589 = 12770
Showing the first eight; more decompositions exist.
