Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449362, here are decompositions:

3 + 31449359 = 31449362
73 + 31449289 = 31449362
103 + 31449259 = 31449362
199 + 31449163 = 31449362
463 + 31448899 = 31449362
499 + 31448863 = 31449362
523 + 31448839 = 31449362
541 + 31448821 = 31449362

Showing the first eight; more decompositions exist.
