Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544480, here are decompositions:

109 + 31544371 = 31544480
157 + 31544323 = 31544480
199 + 31544281 = 31544480
313 + 31544167 = 31544480
349 + 31544131 = 31544480
439 + 31544041 = 31544480
577 + 31543903 = 31544480
607 + 31543873 = 31544480

Showing the first eight; more decompositions exist.
