Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472654, here are decompositions:

43 + 31472611 = 31472654
67 + 31472587 = 31472654
463 + 31472191 = 31472654
487 + 31472167 = 31472654
523 + 31472131 = 31472654
547 + 31472107 = 31472654
601 + 31472053 = 31472654
613 + 31472041 = 31472654

Showing the first eight; more decompositions exist.
