Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495844, here are decompositions:

43 + 31495801 = 31495844
103 + 31495741 = 31495844
151 + 31495693 = 31495844
181 + 31495663 = 31495844
241 + 31495603 = 31495844
397 + 31495447 = 31495844
421 + 31495423 = 31495844
487 + 31495357 = 31495844

Showing the first eight; more decompositions exist.
