Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971990, here are decompositions:
- 47 + 4294971943 = 4294971990
- 53 + 4294971937 = 4294971990
- 59 + 4294971931 = 4294971990
- 61 + 4294971929 = 4294971990
- 107 + 4294971883 = 4294971990
- 131 + 4294971859 = 4294971990
- 149 + 4294971841 = 4294971990
- 317 + 4294971673 = 4294971990
Showing the first eight; more decompositions exist.
