Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77924, here are decompositions:
- 31 + 77893 = 77924
- 61 + 77863 = 77924
- 127 + 77797 = 77924
- 151 + 77773 = 77924
- 163 + 77761 = 77924
- 181 + 77743 = 77924
- 193 + 77731 = 77924
- 211 + 77713 = 77924
Showing the first eight; more decompositions exist.
