Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90142, here are decompositions:
- 53 + 90089 = 90142
- 71 + 90071 = 90142
- 83 + 90059 = 90142
- 89 + 90053 = 90142
- 131 + 90011 = 90142
- 179 + 89963 = 90142
- 233 + 89909 = 90142
- 251 + 89891 = 90142
Showing the first eight; more decompositions exist.
