Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538272, here are decompositions:
- 5 + 538267 = 538272
- 13 + 538259 = 538272
- 23 + 538249 = 538272
- 71 + 538201 = 538272
- 73 + 538199 = 538272
- 109 + 538163 = 538272
- 113 + 538159 = 538272
- 149 + 538123 = 538272
Showing the first eight; more decompositions exist.
