Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554710, here are decompositions:

43 + 31554667 = 31554710
73 + 31554637 = 31554710
79 + 31554631 = 31554710
97 + 31554613 = 31554710
127 + 31554583 = 31554710
139 + 31554571 = 31554710
193 + 31554517 = 31554710
199 + 31554511 = 31554710

Showing the first eight; more decompositions exist.
