Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27672, here are decompositions:
- 19 + 27653 = 27672
- 41 + 27631 = 27672
- 61 + 27611 = 27672
- 89 + 27583 = 27672
- 131 + 27541 = 27672
- 163 + 27509 = 27672
- 191 + 27481 = 27672
- 193 + 27479 = 27672
Showing the first eight; more decompositions exist.
