Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77990, here are decompositions:
- 7 + 77983 = 77990
- 13 + 77977 = 77990
- 61 + 77929 = 77990
- 97 + 77893 = 77990
- 127 + 77863 = 77990
- 151 + 77839 = 77990
- 193 + 77797 = 77990
- 229 + 77761 = 77990
Showing the first eight; more decompositions exist.
