Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574444, here are decompositions:

7 + 31574437 = 31574444
211 + 31574233 = 31574444
241 + 31574203 = 31574444
271 + 31574173 = 31574444
313 + 31574131 = 31574444
337 + 31574107 = 31574444
373 + 31574071 = 31574444
397 + 31574047 = 31574444

Showing the first eight; more decompositions exist.
