Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466002, here are decompositions:

3 + 31465999 = 31466002
23 + 31465979 = 31466002
173 + 31465829 = 31466002
353 + 31465649 = 31466002
383 + 31465619 = 31466002
401 + 31465601 = 31466002
431 + 31465571 = 31466002
521 + 31465481 = 31466002

Showing the first eight; more decompositions exist.
