Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622804, here are decompositions:

61 + 31622743 = 31622804
163 + 31622641 = 31622804
313 + 31622491 = 31622804
331 + 31622473 = 31622804
337 + 31622467 = 31622804
457 + 31622347 = 31622804
523 + 31622281 = 31622804
547 + 31622257 = 31622804

Showing the first eight; more decompositions exist.
