Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460190, here are decompositions:

17 + 31460173 = 31460190
23 + 31460167 = 31460190
53 + 31460137 = 31460190
61 + 31460129 = 31460190
127 + 31460063 = 31460190
137 + 31460053 = 31460190
173 + 31460017 = 31460190
191 + 31459999 = 31460190

Showing the first eight; more decompositions exist.
