Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742236, here are decompositions:

43 + 8742193 = 8742236
67 + 8742169 = 8742236
79 + 8742157 = 8742236
103 + 8742133 = 8742236
199 + 8742037 = 8742236
313 + 8741923 = 8742236
397 + 8741839 = 8742236
439 + 8741797 = 8742236

Showing the first eight; more decompositions exist.
