Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537996, here are decompositions:

107 + 31537889 = 31537996
137 + 31537859 = 31537996
173 + 31537823 = 31537996
449 + 31537547 = 31537996
563 + 31537433 = 31537996
587 + 31537409 = 31537996
683 + 31537313 = 31537996
773 + 31537223 = 31537996

Showing the first eight; more decompositions exist.
