Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146638, here are decompositions:
- 29 + 146609 = 146638
- 257 + 146381 = 146638
- 269 + 146369 = 146638
- 347 + 146291 = 146638
- 389 + 146249 = 146638
- 521 + 146117 = 146638
- 587 + 146051 = 146638
- 617 + 146021 = 146638
Showing the first eight; more decompositions exist.
