Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473136, here are decompositions:

29 + 31473107 = 31473136
53 + 31473083 = 31473136
59 + 31473077 = 31473136
173 + 31472963 = 31473136
257 + 31472879 = 31473136
269 + 31472867 = 31473136
467 + 31472669 = 31473136
503 + 31472633 = 31473136

Showing the first eight; more decompositions exist.
