Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590876, here are decompositions:

29 + 31590847 = 31590876
43 + 31590833 = 31590876
73 + 31590803 = 31590876
113 + 31590763 = 31590876
137 + 31590739 = 31590876
139 + 31590737 = 31590876
193 + 31590683 = 31590876
227 + 31590649 = 31590876

Showing the first eight; more decompositions exist.
