Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740172, here are decompositions:

3 + 8740169 = 8740172
43 + 8740129 = 8740172
61 + 8740111 = 8740172
211 + 8739961 = 8740172
271 + 8739901 = 8740172
349 + 8739823 = 8740172
433 + 8739739 = 8740172
499 + 8739673 = 8740172

Showing the first eight; more decompositions exist.
