Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40272, here are decompositions:
- 19 + 40253 = 40272
- 31 + 40241 = 40272
- 41 + 40231 = 40272
- 59 + 40213 = 40272
- 79 + 40193 = 40272
- 83 + 40189 = 40272
- 103 + 40169 = 40272
- 109 + 40163 = 40272
Showing the first eight; more decompositions exist.
