Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574604, here are decompositions:

41 + 31574563 = 31574604
73 + 31574531 = 31574604
97 + 31574507 = 31574604
107 + 31574497 = 31574604
137 + 31574467 = 31574604
151 + 31574453 = 31574604
167 + 31574437 = 31574604
241 + 31574363 = 31574604

Showing the first eight; more decompositions exist.
