Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472588, here are decompositions:

109 + 31472479 = 31472588
139 + 31472449 = 31472588
151 + 31472437 = 31472588
229 + 31472359 = 31472588
349 + 31472239 = 31472588
379 + 31472209 = 31472588
397 + 31472191 = 31472588
409 + 31472179 = 31472588

Showing the first eight; more decompositions exist.
