Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465634, here are decompositions:

3 + 31465631 = 31465634
73 + 31465561 = 31465634
271 + 31465363 = 31465634
313 + 31465321 = 31465634
457 + 31465177 = 31465634
523 + 31465111 = 31465634
601 + 31465033 = 31465634
631 + 31465003 = 31465634

Showing the first eight; more decompositions exist.
