Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142474, here are decompositions:
- 5 + 142469 = 142474
- 41 + 142433 = 142474
- 47 + 142427 = 142474
- 53 + 142421 = 142474
- 71 + 142403 = 142474
- 83 + 142391 = 142474
- 251 + 142223 = 142474
- 257 + 142217 = 142474
Showing the first eight; more decompositions exist.
