Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731122, here are decompositions:
- 11 + 8731111 = 8731122
- 13 + 8731109 = 8731122
- 19 + 8731103 = 8731122
- 53 + 8731069 = 8731122
- 83 + 8731039 = 8731122
- 139 + 8730983 = 8731122
- 173 + 8730949 = 8731122
- 193 + 8730929 = 8731122
Showing the first eight; more decompositions exist.
