Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544130, here are decompositions:

31 + 31544099 = 31544130
41 + 31544089 = 31544130
53 + 31544077 = 31544130
73 + 31544057 = 31544130
89 + 31544041 = 31544130
97 + 31544033 = 31544130
109 + 31544021 = 31544130
139 + 31543991 = 31544130

Showing the first eight; more decompositions exist.
