Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40430, here are decompositions:

3 + 40427 = 40430
7 + 40423 = 40430
43 + 40387 = 40430
73 + 40357 = 40430
79 + 40351 = 40430
193 + 40237 = 40430
199 + 40231 = 40430
241 + 40189 = 40430

Showing the first eight; more decompositions exist.
