Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294955142, here are decompositions:
- 11 + 4294955131 = 4294955142
- 29 + 4294955113 = 4294955142
- 83 + 4294955059 = 4294955142
- 89 + 4294955053 = 4294955142
- 139 + 4294955003 = 4294955142
- 151 + 4294954991 = 4294955142
- 199 + 4294954943 = 4294955142
- 263 + 4294954879 = 4294955142
Showing the first eight; more decompositions exist.
