Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574504, here are decompositions:

7 + 31574497 = 31574504
37 + 31574467 = 31574504
61 + 31574443 = 31574504
67 + 31574437 = 31574504
271 + 31574233 = 31574504
331 + 31574173 = 31574504
373 + 31574131 = 31574504
397 + 31574107 = 31574504

Showing the first eight; more decompositions exist.
