Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553410, here are decompositions:

23 + 31553387 = 31553410
41 + 31553369 = 31553410
59 + 31553351 = 31553410
71 + 31553339 = 31553410
89 + 31553321 = 31553410
131 + 31553279 = 31553410
137 + 31553273 = 31553410
149 + 31553261 = 31553410

Showing the first eight; more decompositions exist.
