Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544348, here are decompositions:

37 + 31544311 = 31544348
67 + 31544281 = 31544348
127 + 31544221 = 31544348
181 + 31544167 = 31544348
271 + 31544077 = 31544348
307 + 31544041 = 31544348
337 + 31544011 = 31544348
421 + 31543927 = 31544348

Showing the first eight; more decompositions exist.
