Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468460, here are decompositions:

7 + 31468453 = 31468460
13 + 31468447 = 31468460
61 + 31468399 = 31468460
229 + 31468231 = 31468460
313 + 31468147 = 31468460
433 + 31468027 = 31468460
523 + 31467937 = 31468460
607 + 31467853 = 31468460

Showing the first eight; more decompositions exist.
