Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660742, here are decompositions:
- 19 + 8660723 = 8660742
- 43 + 8660699 = 8660742
- 53 + 8660689 = 8660742
- 59 + 8660683 = 8660742
- 61 + 8660681 = 8660742
- 71 + 8660671 = 8660742
- 89 + 8660653 = 8660742
- 131 + 8660611 = 8660742
Showing the first eight; more decompositions exist.
