Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739258, here are decompositions:

61 + 8739197 = 8739258
71 + 8739187 = 8739258
89 + 8739169 = 8739258
131 + 8739127 = 8739258
139 + 8739119 = 8739258
179 + 8739079 = 8739258
251 + 8739007 = 8739258
257 + 8739001 = 8739258

Showing the first eight; more decompositions exist.
