Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739432, here are decompositions:

41 + 8739391 = 8739432
43 + 8739389 = 8739432
73 + 8739359 = 8739432
83 + 8739349 = 8739432
101 + 8739331 = 8739432
151 + 8739281 = 8739432
223 + 8739209 = 8739432
239 + 8739193 = 8739432

Showing the first eight; more decompositions exist.
