Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27742, here are decompositions:
- 3 + 27739 = 27742
- 5 + 27737 = 27742
- 41 + 27701 = 27742
- 53 + 27689 = 27742
- 89 + 27653 = 27742
- 131 + 27611 = 27742
- 191 + 27551 = 27742
- 233 + 27509 = 27742
Showing the first eight; more decompositions exist.
