Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528698, here are decompositions:

29 + 31528669 = 31528698
139 + 31528559 = 31528698
151 + 31528547 = 31528698
167 + 31528531 = 31528698
197 + 31528501 = 31528698
199 + 31528499 = 31528698
239 + 31528459 = 31528698
251 + 31528447 = 31528698

Showing the first eight; more decompositions exist.
