Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463636, here are decompositions:

103 + 31463533 = 31463636
109 + 31463527 = 31463636
229 + 31463407 = 31463636
283 + 31463353 = 31463636
307 + 31463329 = 31463636
367 + 31463269 = 31463636
409 + 31463227 = 31463636
433 + 31463203 = 31463636

Showing the first eight; more decompositions exist.
