Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576342, here are decompositions:

53 + 31576289 = 31576342
59 + 31576283 = 31576342
89 + 31576253 = 31576342
101 + 31576241 = 31576342
131 + 31576211 = 31576342
173 + 31576169 = 31576342
179 + 31576163 = 31576342
251 + 31576091 = 31576342

Showing the first eight; more decompositions exist.
