Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574462, here are decompositions:

13 + 31574449 = 31574462
19 + 31574443 = 31574462
43 + 31574419 = 31574462
229 + 31574233 = 31574462
331 + 31574131 = 31574462
421 + 31574041 = 31574462
463 + 31573999 = 31574462
631 + 31573831 = 31574462

Showing the first eight; more decompositions exist.
