Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473022, here are decompositions:

59 + 31472963 = 31473022
131 + 31472891 = 31473022
173 + 31472849 = 31473022
353 + 31472669 = 31473022
359 + 31472663 = 31473022
389 + 31472633 = 31473022
431 + 31472591 = 31473022
521 + 31472501 = 31473022

Showing the first eight; more decompositions exist.
