Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73442, here are decompositions:
- 73 + 73369 = 73442
- 79 + 73363 = 73442
- 139 + 73303 = 73442
- 151 + 73291 = 73442
- 199 + 73243 = 73442
- 379 + 73063 = 73442
- 433 + 73009 = 73442
- 541 + 72901 = 73442
Showing the first eight; more decompositions exist.
