Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667142, here are decompositions:

5 + 8667137 = 8667142
149 + 8666993 = 8667142
251 + 8666891 = 8667142
293 + 8666849 = 8667142
359 + 8666783 = 8667142
431 + 8666711 = 8667142
461 + 8666681 = 8667142
599 + 8666543 = 8667142

Showing the first eight; more decompositions exist.
