Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544898, here are decompositions:

19 + 31544879 = 31544898
41 + 31544857 = 31544898
71 + 31544827 = 31544898
79 + 31544819 = 31544898
127 + 31544771 = 31544898
139 + 31544759 = 31544898
149 + 31544749 = 31544898
179 + 31544719 = 31544898

Showing the first eight; more decompositions exist.
