Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472570, here are decompositions:

211 + 31472359 = 31472570
277 + 31472293 = 31472570
331 + 31472239 = 31472570
379 + 31472191 = 31472570
421 + 31472149 = 31472570
439 + 31472131 = 31472570
463 + 31472107 = 31472570
541 + 31472029 = 31472570

Showing the first eight; more decompositions exist.
