Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63138, here are decompositions:
- 7 + 63131 = 63138
- 11 + 63127 = 63138
- 41 + 63097 = 63138
- 59 + 63079 = 63138
- 71 + 63067 = 63138
- 79 + 63059 = 63138
- 107 + 63031 = 63138
- 109 + 63029 = 63138
Showing the first eight; more decompositions exist.
