Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745750, here are decompositions:
- 7 + 8745743 = 8745750
- 47 + 8745703 = 8745750
- 53 + 8745697 = 8745750
- 67 + 8745683 = 8745750
- 71 + 8745679 = 8745750
- 73 + 8745677 = 8745750
- 113 + 8745637 = 8745750
- 137 + 8745613 = 8745750
Showing the first eight; more decompositions exist.
