Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623590, here are decompositions:

67 + 31623523 = 31623590
79 + 31623511 = 31623590
109 + 31623481 = 31623590
151 + 31623439 = 31623590
367 + 31623223 = 31623590
379 + 31623211 = 31623590
409 + 31623181 = 31623590
421 + 31623169 = 31623590

Showing the first eight; more decompositions exist.
