Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576326, here are decompositions:

37 + 31576289 = 31576326
43 + 31576283 = 31576326
59 + 31576267 = 31576326
73 + 31576253 = 31576326
107 + 31576219 = 31576326
127 + 31576199 = 31576326
139 + 31576187 = 31576326
157 + 31576169 = 31576326

Showing the first eight; more decompositions exist.
