Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63240, here are decompositions:
- 29 + 63211 = 63240
- 41 + 63199 = 63240
- 43 + 63197 = 63240
- 61 + 63179 = 63240
- 109 + 63131 = 63240
- 113 + 63127 = 63240
- 127 + 63113 = 63240
- 137 + 63103 = 63240
Showing the first eight; more decompositions exist.
