Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460382, here are decompositions:

13 + 31460369 = 31460382
43 + 31460339 = 31460382
53 + 31460329 = 31460382
61 + 31460321 = 31460382
89 + 31460293 = 31460382
101 + 31460281 = 31460382
103 + 31460279 = 31460382
383 + 31459999 = 31460382

Showing the first eight; more decompositions exist.
