Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70420, here are decompositions:
- 41 + 70379 = 70420
- 47 + 70373 = 70420
- 107 + 70313 = 70420
- 131 + 70289 = 70420
- 149 + 70271 = 70420
- 179 + 70241 = 70420
- 191 + 70229 = 70420
- 197 + 70223 = 70420
Showing the first eight; more decompositions exist.
