Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496144, here are decompositions:

3 + 31496141 = 31496144
61 + 31496083 = 31496144
103 + 31496041 = 31496144
223 + 31495921 = 31496144
487 + 31495657 = 31496144
541 + 31495603 = 31496144
643 + 31495501 = 31496144
727 + 31495417 = 31496144

Showing the first eight; more decompositions exist.
