Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448362, here are decompositions:

41 + 31448321 = 31448362
53 + 31448309 = 31448362
59 + 31448303 = 31448362
191 + 31448171 = 31448362
251 + 31448111 = 31448362
293 + 31448069 = 31448362
401 + 31447961 = 31448362
431 + 31447931 = 31448362

Showing the first eight; more decompositions exist.
