Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 35720, here are decompositions:
- 43 + 35677 = 35720
- 103 + 35617 = 35720
- 127 + 35593 = 35720
- 151 + 35569 = 35720
- 193 + 35527 = 35720
- 199 + 35521 = 35720
- 211 + 35509 = 35720
- 229 + 35491 = 35720
Showing the first eight; more decompositions exist.
