Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951880, here are decompositions:

29 + 951851 = 951880
89 + 951791 = 951880
131 + 951749 = 951880
191 + 951689 = 951880
233 + 951647 = 951880
239 + 951641 = 951880
257 + 951623 = 951880
383 + 951497 = 951880

Showing the first eight; more decompositions exist.
