Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539846, here are decompositions:

7 + 31539839 = 31539846
29 + 31539817 = 31539846
83 + 31539763 = 31539846
89 + 31539757 = 31539846
109 + 31539737 = 31539846
139 + 31539707 = 31539846
197 + 31539649 = 31539846
263 + 31539583 = 31539846

Showing the first eight; more decompositions exist.
