Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599802, here are decompositions:

29 + 31599773 = 31599802
41 + 31599761 = 31599802
131 + 31599671 = 31599802
149 + 31599653 = 31599802
173 + 31599629 = 31599802
191 + 31599611 = 31599802
239 + 31599563 = 31599802
251 + 31599551 = 31599802

Showing the first eight; more decompositions exist.
