Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574370, here are decompositions:

7 + 31574363 = 31574370
41 + 31574329 = 31574370
43 + 31574327 = 31574370
67 + 31574303 = 31574370
73 + 31574297 = 31574370
109 + 31574261 = 31574370
137 + 31574233 = 31574370
167 + 31574203 = 31574370

Showing the first eight; more decompositions exist.
