Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480584, here are decompositions:

151 + 31480433 = 31480584
193 + 31480391 = 31480584
211 + 31480373 = 31480584
383 + 31480201 = 31480584
467 + 31480117 = 31480584
523 + 31480061 = 31480584
563 + 31480021 = 31480584
727 + 31479857 = 31480584

Showing the first eight; more decompositions exist.
