Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137770, here are decompositions:
- 47 + 137723 = 137770
- 71 + 137699 = 137770
- 131 + 137639 = 137770
- 137 + 137633 = 137770
- 173 + 137597 = 137770
- 197 + 137573 = 137770
- 233 + 137537 = 137770
- 251 + 137519 = 137770
Showing the first eight; more decompositions exist.
