Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947390, here are decompositions:

7 + 947383 = 947390
13 + 947377 = 947390
127 + 947263 = 947390
151 + 947239 = 947390
193 + 947197 = 947390
271 + 947119 = 947390
307 + 947083 = 947390
397 + 946993 = 947390

Showing the first eight; more decompositions exist.
