Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732140, here are decompositions:
- 3 + 8732137 = 8732140
- 17 + 8732123 = 8732140
- 23 + 8732117 = 8732140
- 47 + 8732093 = 8732140
- 59 + 8732081 = 8732140
- 89 + 8732051 = 8732140
- 113 + 8732027 = 8732140
- 149 + 8731991 = 8732140
Showing the first eight; more decompositions exist.
