Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947290, here are decompositions:

107 + 947183 = 947290
257 + 947033 = 947290
263 + 947027 = 947290
293 + 946997 = 947290
347 + 946943 = 947290
359 + 946931 = 947290
389 + 946901 = 947290
431 + 946859 = 947290

Showing the first eight; more decompositions exist.
