Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460246, here are decompositions:

73 + 31460173 = 31460246
79 + 31460167 = 31460246
109 + 31460137 = 31460246
193 + 31460053 = 31460246
229 + 31460017 = 31460246
283 + 31459963 = 31460246
397 + 31459849 = 31460246
439 + 31459807 = 31460246

Showing the first eight; more decompositions exist.
