Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474544, here are decompositions:

43 + 31474501 = 31474544
181 + 31474363 = 31474544
193 + 31474351 = 31474544
331 + 31474213 = 31474544
373 + 31474171 = 31474544
433 + 31474111 = 31474544
487 + 31474057 = 31474544
613 + 31473931 = 31474544

Showing the first eight; more decompositions exist.
