Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85442, here are decompositions:
- 3 + 85439 = 85442
- 13 + 85429 = 85442
- 31 + 85411 = 85442
- 61 + 85381 = 85442
- 73 + 85369 = 85442
- 79 + 85363 = 85442
- 109 + 85333 = 85442
- 139 + 85303 = 85442
Showing the first eight; more decompositions exist.
