Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743140, here are decompositions:
- 19 + 8743121 = 8743140
- 37 + 8743103 = 8743140
- 41 + 8743099 = 8743140
- 53 + 8743087 = 8743140
- 61 + 8743079 = 8743140
- 73 + 8743067 = 8743140
- 97 + 8743043 = 8743140
- 103 + 8743037 = 8743140
Showing the first eight; more decompositions exist.
