Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599850, here are decompositions:

41 + 31599809 = 31599850
83 + 31599767 = 31599850
89 + 31599761 = 31599850
167 + 31599683 = 31599850
179 + 31599671 = 31599850
197 + 31599653 = 31599850
239 + 31599611 = 31599850
251 + 31599599 = 31599850

Showing the first eight; more decompositions exist.
