Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472534, here are decompositions:

97 + 31472437 = 31472534
241 + 31472293 = 31472534
367 + 31472167 = 31472534
523 + 31472011 = 31472534
601 + 31471933 = 31472534
823 + 31471711 = 31472534
853 + 31471681 = 31472534
1123 + 31471411 = 31472534

Showing the first eight; more decompositions exist.
