Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947242, here are decompositions:

3 + 947239 = 947242
59 + 947183 = 947242
71 + 947171 = 947242
113 + 947129 = 947242
281 + 946961 = 947242
293 + 946949 = 947242
311 + 946931 = 947242
383 + 946859 = 947242

Showing the first eight; more decompositions exist.
