Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577536, here are decompositions:

5 + 31577531 = 31577536
149 + 31577387 = 31577536
167 + 31577369 = 31577536
173 + 31577363 = 31577536
479 + 31577057 = 31577536
569 + 31576967 = 31577536
587 + 31576949 = 31577536
647 + 31576889 = 31577536

Showing the first eight; more decompositions exist.
