Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544510, here are decompositions:

139 + 31544371 = 31544510
163 + 31544347 = 31544510
199 + 31544311 = 31544510
229 + 31544281 = 31544510
331 + 31544179 = 31544510
379 + 31544131 = 31544510
421 + 31544089 = 31544510
433 + 31544077 = 31544510

Showing the first eight; more decompositions exist.
