Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31328, here are decompositions:
- 7 + 31321 = 31328
- 61 + 31267 = 31328
- 79 + 31249 = 31328
- 97 + 31231 = 31328
- 109 + 31219 = 31328
- 139 + 31189 = 31328
- 151 + 31177 = 31328
- 181 + 31147 = 31328
Showing the first eight; more decompositions exist.
