Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49042, here are decompositions:
- 5 + 49037 = 49042
- 11 + 49031 = 49042
- 23 + 49019 = 49042
- 53 + 48989 = 49042
- 89 + 48953 = 49042
- 173 + 48869 = 49042
- 233 + 48809 = 49042
- 263 + 48779 = 49042
Showing the first eight; more decompositions exist.
