Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186042, here are decompositions:
- 5 + 186037 = 186042
- 19 + 186023 = 186042
- 23 + 186019 = 186042
- 29 + 186013 = 186042
- 71 + 185971 = 186042
- 83 + 185959 = 186042
- 139 + 185903 = 186042
- 149 + 185893 = 186042
Showing the first eight; more decompositions exist.
