Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574100, here are decompositions:

7 + 31574093 = 31574100
29 + 31574071 = 31574100
53 + 31574047 = 31574100
59 + 31574041 = 31574100
79 + 31574021 = 31574100
101 + 31573999 = 31574100
139 + 31573961 = 31574100
241 + 31573859 = 31574100

Showing the first eight; more decompositions exist.
