Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466050, here are decompositions:

47 + 31466003 = 31466050
71 + 31465979 = 31466050
269 + 31465781 = 31466050
293 + 31465757 = 31466050
353 + 31465697 = 31466050
389 + 31465661 = 31466050
401 + 31465649 = 31466050
419 + 31465631 = 31466050

Showing the first eight; more decompositions exist.
