Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12042, here are decompositions:
- 5 + 12037 = 12042
- 31 + 12011 = 12042
- 61 + 11981 = 12042
- 71 + 11971 = 12042
- 73 + 11969 = 12042
- 83 + 11959 = 12042
- 89 + 11953 = 12042
- 101 + 11941 = 12042
Showing the first eight; more decompositions exist.
