Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473658, here are decompositions:

59 + 31473599 = 31473658
179 + 31473479 = 31473658
449 + 31473209 = 31473658
467 + 31473191 = 31473658
617 + 31473041 = 31473658
809 + 31472849 = 31473658
1307 + 31472351 = 31473658
1319 + 31472339 = 31473658

Showing the first eight; more decompositions exist.
