Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130272, here are decompositions:
- 5 + 130267 = 130272
- 11 + 130261 = 130272
- 13 + 130259 = 130272
- 19 + 130253 = 130272
- 31 + 130241 = 130272
- 61 + 130211 = 130272
- 71 + 130201 = 130272
- 73 + 130199 = 130272
Showing the first eight; more decompositions exist.
