Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27972, here are decompositions:
- 5 + 27967 = 27972
- 11 + 27961 = 27972
- 19 + 27953 = 27972
- 29 + 27943 = 27972
- 31 + 27941 = 27972
- 53 + 27919 = 27972
- 71 + 27901 = 27972
- 79 + 27893 = 27972
Showing the first eight; more decompositions exist.
