Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576374, here are decompositions:

7 + 31576367 = 31576374
23 + 31576351 = 31576374
107 + 31576267 = 31576374
113 + 31576261 = 31576374
163 + 31576211 = 31576374
173 + 31576201 = 31576374
211 + 31576163 = 31576374
257 + 31576117 = 31576374

Showing the first eight; more decompositions exist.
