Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 48978, here are decompositions:
- 5 + 48973 = 48978
- 31 + 48947 = 48978
- 71 + 48907 = 48978
- 89 + 48889 = 48978
- 107 + 48871 = 48978
- 109 + 48869 = 48978
- 131 + 48847 = 48978
- 157 + 48821 = 48978
Showing the first eight; more decompositions exist.
