Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544508, here are decompositions:

137 + 31544371 = 31544508
197 + 31544311 = 31544508
211 + 31544297 = 31544508
227 + 31544281 = 31544508
337 + 31544171 = 31544508
409 + 31544099 = 31544508
419 + 31544089 = 31544508
431 + 31544077 = 31544508

Showing the first eight; more decompositions exist.
