Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70900, here are decompositions:

23 + 70877 = 70900
47 + 70853 = 70900
59 + 70841 = 70900
107 + 70793 = 70900
131 + 70769 = 70900
191 + 70709 = 70900
233 + 70667 = 70900
281 + 70619 = 70900

Showing the first eight; more decompositions exist.
