Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622546, here are decompositions:

37 + 31622509 = 31622546
73 + 31622473 = 31622546
79 + 31622467 = 31622546
157 + 31622389 = 31622546
199 + 31622347 = 31622546
367 + 31622179 = 31622546
379 + 31622167 = 31622546
433 + 31622113 = 31622546

Showing the first eight; more decompositions exist.
