Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672992, here are decompositions:
- 23 + 8672969 = 8672992
- 59 + 8672933 = 8672992
- 101 + 8672891 = 8672992
- 131 + 8672861 = 8672992
- 173 + 8672819 = 8672992
- 191 + 8672801 = 8672992
- 269 + 8672723 = 8672992
- 353 + 8672639 = 8672992
Showing the first eight; more decompositions exist.
