Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574498, here are decompositions:

19 + 31574479 = 31574498
31 + 31574467 = 31574498
61 + 31574437 = 31574498
79 + 31574419 = 31574498
367 + 31574131 = 31574498
457 + 31574041 = 31574498
499 + 31573999 = 31574498
541 + 31573957 = 31574498

Showing the first eight; more decompositions exist.
