Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576410, here are decompositions:

7 + 31576403 = 31576410
37 + 31576373 = 31576410
43 + 31576367 = 31576410
59 + 31576351 = 31576410
127 + 31576283 = 31576410
149 + 31576261 = 31576410
157 + 31576253 = 31576410
179 + 31576231 = 31576410

Showing the first eight; more decompositions exist.
