Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620342, here are decompositions:

53 + 8620289 = 8620342
83 + 8620259 = 8620342
131 + 8620211 = 8620342
191 + 8620151 = 8620342
233 + 8620109 = 8620342
293 + 8620049 = 8620342
449 + 8619893 = 8620342
569 + 8619773 = 8620342

Showing the first eight; more decompositions exist.
