Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142044, here are decompositions:
- 5 + 142039 = 142044
- 13 + 142031 = 142044
- 37 + 142007 = 142044
- 53 + 141991 = 142044
- 73 + 141971 = 142044
- 83 + 141961 = 142044
- 103 + 141941 = 142044
- 107 + 141937 = 142044
Showing the first eight; more decompositions exist.
