Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49140, here are decompositions:
- 17 + 49123 = 49140
- 19 + 49121 = 49140
- 23 + 49117 = 49140
- 31 + 49109 = 49140
- 37 + 49103 = 49140
- 59 + 49081 = 49140
- 71 + 49069 = 49140
- 83 + 49057 = 49140
Showing the first eight; more decompositions exist.
