Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731842, here are decompositions:
- 11 + 8731831 = 8731842
- 23 + 8731819 = 8731842
- 59 + 8731783 = 8731842
- 79 + 8731763 = 8731842
- 131 + 8731711 = 8731842
- 181 + 8731661 = 8731842
- 199 + 8731643 = 8731842
- 233 + 8731609 = 8731842
Showing the first eight; more decompositions exist.
