Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472586, here are decompositions:

97 + 31472489 = 31472586
107 + 31472479 = 31472586
137 + 31472449 = 31472586
149 + 31472437 = 31472586
227 + 31472359 = 31472586
293 + 31472293 = 31472586
347 + 31472239 = 31472586
419 + 31472167 = 31472586

Showing the first eight; more decompositions exist.
