Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90042, here are decompositions:
- 11 + 90031 = 90042
- 19 + 90023 = 90042
- 23 + 90019 = 90042
- 31 + 90011 = 90042
- 41 + 90001 = 90042
- 53 + 89989 = 90042
- 59 + 89983 = 90042
- 79 + 89963 = 90042
Showing the first eight; more decompositions exist.
