Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135042, here are decompositions:
- 13 + 135029 = 135042
- 23 + 135019 = 135042
- 43 + 134999 = 135042
- 53 + 134989 = 135042
- 191 + 134851 = 135042
- 311 + 134731 = 135042
- 359 + 134683 = 135042
- 373 + 134669 = 135042
Showing the first eight; more decompositions exist.
