Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91442, here are decompositions:
- 19 + 91423 = 91442
- 31 + 91411 = 91442
- 61 + 91381 = 91442
- 73 + 91369 = 91442
- 139 + 91303 = 91442
- 151 + 91291 = 91442
- 193 + 91249 = 91442
- 199 + 91243 = 91442
Showing the first eight; more decompositions exist.
