Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947642, here are decompositions:

103 + 947539 = 947642
193 + 947449 = 947642
211 + 947431 = 947642
229 + 947413 = 947642
379 + 947263 = 947642
439 + 947203 = 947642
523 + 947119 = 947642
673 + 946969 = 947642

Showing the first eight; more decompositions exist.
