Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473526, here are decompositions:

3 + 31473523 = 31473526
47 + 31473479 = 31473526
89 + 31473437 = 31473526
113 + 31473413 = 31473526
167 + 31473359 = 31473526
263 + 31473263 = 31473526
317 + 31473209 = 31473526
353 + 31473173 = 31473526

Showing the first eight; more decompositions exist.
