Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618742, here are decompositions:
- 5 + 8618737 = 8618742
- 43 + 8618699 = 8618742
- 53 + 8618689 = 8618742
- 59 + 8618683 = 8618742
- 61 + 8618681 = 8618742
- 103 + 8618639 = 8618742
- 149 + 8618593 = 8618742
- 151 + 8618591 = 8618742
Showing the first eight; more decompositions exist.
