Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78972, here are decompositions:
- 31 + 78941 = 78972
- 43 + 78929 = 78972
- 53 + 78919 = 78972
- 71 + 78901 = 78972
- 79 + 78893 = 78972
- 83 + 78889 = 78972
- 149 + 78823 = 78972
- 163 + 78809 = 78972
Showing the first eight; more decompositions exist.
