Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740212, here are decompositions:

29 + 8740183 = 8740212
43 + 8740169 = 8740212
73 + 8740139 = 8740212
83 + 8740129 = 8740212
101 + 8740111 = 8740212
251 + 8739961 = 8740212
293 + 8739919 = 8740212
311 + 8739901 = 8740212

Showing the first eight; more decompositions exist.
