Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740258, here are decompositions:

71 + 8740187 = 8740258
89 + 8740169 = 8740258
101 + 8740157 = 8740258
347 + 8739911 = 8740258
389 + 8739869 = 8740258
431 + 8739827 = 8740258
491 + 8739767 = 8740258
509 + 8739749 = 8740258

Showing the first eight; more decompositions exist.
