Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47042, here are decompositions:
- 109 + 46933 = 47042
- 181 + 46861 = 47042
- 211 + 46831 = 47042
- 223 + 46819 = 47042
- 271 + 46771 = 47042
- 379 + 46663 = 47042
- 409 + 46633 = 47042
- 571 + 46471 = 47042
Showing the first eight; more decompositions exist.
