Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576270, here are decompositions:

3 + 31576267 = 31576270
17 + 31576253 = 31576270
29 + 31576241 = 31576270
59 + 31576211 = 31576270
71 + 31576199 = 31576270
83 + 31576187 = 31576270
101 + 31576169 = 31576270
107 + 31576163 = 31576270

Showing the first eight; more decompositions exist.
