Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74442, here are decompositions:
- 23 + 74419 = 74442
- 29 + 74413 = 74442
- 31 + 74411 = 74442
- 59 + 74383 = 74442
- 61 + 74381 = 74442
- 79 + 74363 = 74442
- 89 + 74353 = 74442
- 131 + 74311 = 74442
Showing the first eight; more decompositions exist.
