Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86042, here are decompositions:
- 13 + 86029 = 86042
- 31 + 86011 = 86042
- 43 + 85999 = 86042
- 109 + 85933 = 86042
- 139 + 85903 = 86042
- 199 + 85843 = 86042
- 211 + 85831 = 86042
- 223 + 85819 = 86042
Showing the first eight; more decompositions exist.
