Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472354, here are decompositions:

3 + 31472351 = 31472354
61 + 31472293 = 31472354
163 + 31472191 = 31472354
211 + 31472143 = 31472354
223 + 31472131 = 31472354
313 + 31472041 = 31472354
421 + 31471933 = 31472354
523 + 31471831 = 31472354

Showing the first eight; more decompositions exist.
