Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576358, here are decompositions:

7 + 31576351 = 31576358
97 + 31576261 = 31576358
127 + 31576231 = 31576358
139 + 31576219 = 31576358
157 + 31576201 = 31576358
241 + 31576117 = 31576358
271 + 31576087 = 31576358
349 + 31576009 = 31576358

Showing the first eight; more decompositions exist.
