Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77972, here are decompositions:
- 3 + 77969 = 77972
- 43 + 77929 = 77972
- 73 + 77899 = 77972
- 79 + 77893 = 77972
- 109 + 77863 = 77972
- 199 + 77773 = 77972
- 211 + 77761 = 77972
- 229 + 77743 = 77972
Showing the first eight; more decompositions exist.
