Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472396, here are decompositions:

37 + 31472359 = 31472396
103 + 31472293 = 31472396
157 + 31472239 = 31472396
229 + 31472167 = 31472396
367 + 31472029 = 31472396
457 + 31471939 = 31472396
463 + 31471933 = 31472396
547 + 31471849 = 31472396

Showing the first eight; more decompositions exist.
