Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961138, here are decompositions:
- 19 + 4294961119 = 4294961138
- 67 + 4294961071 = 4294961138
- 157 + 4294960981 = 4294961138
- 379 + 4294960759 = 4294961138
- 577 + 4294960561 = 4294961138
- 691 + 4294960447 = 4294961138
- 739 + 4294960399 = 4294961138
- 877 + 4294960261 = 4294961138
Showing the first eight; more decompositions exist.
