Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143228, here are decompositions:
- 31 + 143197 = 143228
- 331 + 142897 = 143228
- 439 + 142789 = 143228
- 457 + 142771 = 143228
- 571 + 142657 = 143228
- 619 + 142609 = 143228
- 661 + 142567 = 143228
- 691 + 142537 = 143228
Showing the first eight; more decompositions exist.
