Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474952, here are decompositions:

79 + 31474873 = 31474952
151 + 31474801 = 31474952
283 + 31474669 = 31474952
433 + 31474519 = 31474952
463 + 31474489 = 31474952
601 + 31474351 = 31474952
661 + 31474291 = 31474952
739 + 31474213 = 31474952

Showing the first eight; more decompositions exist.
