Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55142, here are decompositions:
- 163 + 54979 = 55142
- 193 + 54949 = 55142
- 223 + 54919 = 55142
- 313 + 54829 = 55142
- 421 + 54721 = 55142
- 433 + 54709 = 55142
- 463 + 54679 = 55142
- 541 + 54601 = 55142
Showing the first eight; more decompositions exist.
