Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958142, here are decompositions:
- 11 + 4294958131 = 4294958142
- 43 + 4294958099 = 4294958142
- 71 + 4294958071 = 4294958142
- 73 + 4294958069 = 4294958142
- 131 + 4294958011 = 4294958142
- 151 + 4294957991 = 4294958142
- 199 + 4294957943 = 4294958142
- 239 + 4294957903 = 4294958142
Showing the first eight; more decompositions exist.
