Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74220, here are decompositions:
- 11 + 74209 = 74220
- 17 + 74203 = 74220
- 19 + 74201 = 74220
- 23 + 74197 = 74220
- 31 + 74189 = 74220
- 43 + 74177 = 74220
- 53 + 74167 = 74220
- 59 + 74161 = 74220
Showing the first eight; more decompositions exist.
