Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54142, here are decompositions:
- 3 + 54139 = 54142
- 41 + 54101 = 54142
- 59 + 54083 = 54142
- 83 + 54059 = 54142
- 131 + 54011 = 54142
- 149 + 53993 = 54142
- 191 + 53951 = 54142
- 251 + 53891 = 54142
Showing the first eight; more decompositions exist.
