Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574318, here are decompositions:

211 + 31574107 = 31574318
271 + 31574047 = 31574318
277 + 31574041 = 31574318
487 + 31573831 = 31574318
499 + 31573819 = 31574318
571 + 31573747 = 31574318
691 + 31573627 = 31574318
757 + 31573561 = 31574318

Showing the first eight; more decompositions exist.
