Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70428, here are decompositions:
- 5 + 70423 = 70428
- 47 + 70381 = 70428
- 101 + 70327 = 70428
- 107 + 70321 = 70428
- 131 + 70297 = 70428
- 139 + 70289 = 70428
- 157 + 70271 = 70428
- 179 + 70249 = 70428
Showing the first eight; more decompositions exist.
