Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466236, here are decompositions:

3 + 31466233 = 31466236
29 + 31466207 = 31466236
173 + 31466063 = 31466236
233 + 31466003 = 31466236
257 + 31465979 = 31466236
479 + 31465757 = 31466236
509 + 31465727 = 31466236
563 + 31465673 = 31466236

Showing the first eight; more decompositions exist.
