Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88142, here are decompositions:
- 13 + 88129 = 88142
- 73 + 88069 = 88142
- 139 + 88003 = 88142
- 151 + 87991 = 88142
- 181 + 87961 = 88142
- 199 + 87943 = 88142
- 211 + 87931 = 88142
- 331 + 87811 = 88142
Showing the first eight; more decompositions exist.
