Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473446, here are decompositions:

163 + 31473283 = 31473446
229 + 31473217 = 31473446
283 + 31473163 = 31473446
337 + 31473109 = 31473446
379 + 31473067 = 31473446
409 + 31473037 = 31473446
463 + 31472983 = 31473446
607 + 31472839 = 31473446

Showing the first eight; more decompositions exist.
