Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576148, here are decompositions:

31 + 31576117 = 31576148
61 + 31576087 = 31576148
139 + 31576009 = 31576148
157 + 31575991 = 31576148
211 + 31575937 = 31576148
271 + 31575877 = 31576148
349 + 31575799 = 31576148
379 + 31575769 = 31576148

Showing the first eight; more decompositions exist.
