Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27642, here are decompositions:
- 11 + 27631 = 27642
- 31 + 27611 = 27642
- 59 + 27583 = 27642
- 61 + 27581 = 27642
- 101 + 27541 = 27642
- 103 + 27539 = 27642
- 113 + 27529 = 27642
- 163 + 27479 = 27642
Showing the first eight; more decompositions exist.
