Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489844, here are decompositions:

3 + 31489841 = 31489844
97 + 31489747 = 31489844
181 + 31489663 = 31489844
193 + 31489651 = 31489844
433 + 31489411 = 31489844
601 + 31489243 = 31489844
853 + 31488991 = 31489844
937 + 31488907 = 31489844

Showing the first eight; more decompositions exist.
