Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973890, here are decompositions:
- 23 + 4294973867 = 4294973890
- 47 + 4294973843 = 4294973890
- 59 + 4294973831 = 4294973890
- 131 + 4294973759 = 4294973890
- 173 + 4294973717 = 4294973890
- 239 + 4294973651 = 4294973890
- 257 + 4294973633 = 4294973890
- 353 + 4294973537 = 4294973890
Showing the first eight; more decompositions exist.
