Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147442, here are decompositions:
- 23 + 147419 = 147442
- 41 + 147401 = 147442
- 89 + 147353 = 147442
- 101 + 147341 = 147442
- 131 + 147311 = 147442
- 149 + 147293 = 147442
- 179 + 147263 = 147442
- 233 + 147209 = 147442
Showing the first eight; more decompositions exist.
