Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137638, here are decompositions:
- 5 + 137633 = 137638
- 41 + 137597 = 137638
- 71 + 137567 = 137638
- 101 + 137537 = 137638
- 131 + 137507 = 137638
- 191 + 137447 = 137638
- 239 + 137399 = 137638
- 251 + 137387 = 137638
Showing the first eight; more decompositions exist.
