Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544050, here are decompositions:

11 + 31544039 = 31544050
17 + 31544033 = 31544050
29 + 31544021 = 31544050
53 + 31543997 = 31544050
59 + 31543991 = 31544050
71 + 31543979 = 31544050
89 + 31543961 = 31544050
137 + 31543913 = 31544050

Showing the first eight; more decompositions exist.
