Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473862, here are decompositions:

23 + 31473839 = 31473862
53 + 31473809 = 31473862
83 + 31473779 = 31473862
263 + 31473599 = 31473862
269 + 31473593 = 31473862
281 + 31473581 = 31473862
383 + 31473479 = 31473862
449 + 31473413 = 31473862

Showing the first eight; more decompositions exist.
