Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4272, here are decompositions:
- 11 + 4261 = 4272
- 13 + 4259 = 4272
- 19 + 4253 = 4272
- 29 + 4243 = 4272
- 31 + 4241 = 4272
- 41 + 4231 = 4272
- 43 + 4229 = 4272
- 53 + 4219 = 4272
Showing the first eight; more decompositions exist.
