Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86142, here are decompositions:
- 5 + 86137 = 86142
- 11 + 86131 = 86142
- 29 + 86113 = 86142
- 31 + 86111 = 86142
- 59 + 86083 = 86142
- 73 + 86069 = 86142
- 113 + 86029 = 86142
- 131 + 86011 = 86142
Showing the first eight; more decompositions exist.
