Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472462, here are decompositions:

13 + 31472449 = 31472462
103 + 31472359 = 31472462
223 + 31472239 = 31472462
271 + 31472191 = 31472462
283 + 31472179 = 31472462
313 + 31472149 = 31472462
331 + 31472131 = 31472462
409 + 31472053 = 31472462

Showing the first eight; more decompositions exist.
