Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45210, here are decompositions:

13 + 45197 = 45210
19 + 45191 = 45210
29 + 45181 = 45210
31 + 45179 = 45210
71 + 45139 = 45210
73 + 45137 = 45210
79 + 45131 = 45210
83 + 45127 = 45210

Showing the first eight; more decompositions exist.
