Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742434, here are decompositions:

13 + 8742421 = 8742434
67 + 8742367 = 8742434
241 + 8742193 = 8742434
277 + 8742157 = 8742434
313 + 8742121 = 8742434
331 + 8742103 = 8742434
367 + 8742067 = 8742434
397 + 8742037 = 8742434

Showing the first eight; more decompositions exist.
