Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574964, here are decompositions:

37 + 31574927 = 31574964
53 + 31574911 = 31574964
73 + 31574891 = 31574964
101 + 31574863 = 31574964
103 + 31574861 = 31574964
151 + 31574813 = 31574964
191 + 31574773 = 31574964
241 + 31574723 = 31574964

Showing the first eight; more decompositions exist.
