Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142516, here are decompositions:
- 47 + 142469 = 142516
- 83 + 142433 = 142516
- 89 + 142427 = 142516
- 113 + 142403 = 142516
- 197 + 142319 = 142516
- 293 + 142223 = 142516
- 347 + 142169 = 142516
- 359 + 142157 = 142516
Showing the first eight; more decompositions exist.
