Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658142, here are decompositions:

5 + 8658137 = 8658142
41 + 8658101 = 8658142
83 + 8658059 = 8658142
173 + 8657969 = 8658142
239 + 8657903 = 8658142
293 + 8657849 = 8658142
359 + 8657783 = 8658142
419 + 8657723 = 8658142

Showing the first eight; more decompositions exist.
