Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623794, here are decompositions:

73 + 31623721 = 31623794
127 + 31623667 = 31623794
271 + 31623523 = 31623794
283 + 31623511 = 31623794
313 + 31623481 = 31623794
373 + 31623421 = 31623794
421 + 31623373 = 31623794
457 + 31623337 = 31623794

Showing the first eight; more decompositions exist.
