Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574952, here are decompositions:

41 + 31574911 = 31574952
61 + 31574891 = 31574952
89 + 31574863 = 31574952
103 + 31574849 = 31574952
131 + 31574821 = 31574952
139 + 31574813 = 31574952
173 + 31574779 = 31574952
179 + 31574773 = 31574952

Showing the first eight; more decompositions exist.
