Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571462, here are decompositions:

73 + 31571389 = 31571462
79 + 31571383 = 31571462
271 + 31571191 = 31571462
313 + 31571149 = 31571462
379 + 31571083 = 31571462
463 + 31570999 = 31571462
523 + 31570939 = 31571462
619 + 31570843 = 31571462

Showing the first eight; more decompositions exist.
