Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957442, here are decompositions:
- 3 + 4294957439 = 4294957442
- 43 + 4294957399 = 4294957442
- 73 + 4294957369 = 4294957442
- 541 + 4294956901 = 4294957442
- 613 + 4294956829 = 4294957442
- 691 + 4294956751 = 4294957442
- 829 + 4294956613 = 4294957442
- 1291 + 4294956151 = 4294957442
Showing the first eight; more decompositions exist.
