Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574904, here are decompositions:

13 + 31574891 = 31574904
17 + 31574887 = 31574904
41 + 31574863 = 31574904
43 + 31574861 = 31574904
83 + 31574821 = 31574904
131 + 31574773 = 31574904
157 + 31574747 = 31574904
181 + 31574723 = 31574904

Showing the first eight; more decompositions exist.
