Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37780, here are decompositions:
- 89 + 37691 = 37780
- 131 + 37649 = 37780
- 137 + 37643 = 37780
- 173 + 37607 = 37780
- 191 + 37589 = 37780
- 233 + 37547 = 37780
- 251 + 37529 = 37780
- 263 + 37517 = 37780
Showing the first eight; more decompositions exist.
