Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142190, here are decompositions:
- 7 + 142183 = 142190
- 31 + 142159 = 142190
- 67 + 142123 = 142190
- 79 + 142111 = 142190
- 151 + 142039 = 142190
- 199 + 141991 = 142190
- 229 + 141961 = 142190
- 283 + 141907 = 142190
Showing the first eight; more decompositions exist.
