Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947402, here are decompositions:

13 + 947389 = 947402
19 + 947383 = 947402
61 + 947341 = 947402
103 + 947299 = 947402
139 + 947263 = 947402
163 + 947239 = 947402
199 + 947203 = 947402
283 + 947119 = 947402

Showing the first eight; more decompositions exist.
