Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466746, here are decompositions:

53 + 31466693 = 31466746
89 + 31466657 = 31466746
149 + 31466597 = 31466746
197 + 31466549 = 31466746
359 + 31466387 = 31466746
419 + 31466327 = 31466746
683 + 31466063 = 31466746
743 + 31466003 = 31466746

Showing the first eight; more decompositions exist.
