Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498698, here are decompositions:

41 + 31498657 = 31498698
59 + 31498639 = 31498698
107 + 31498591 = 31498698
139 + 31498559 = 31498698
149 + 31498549 = 31498698
151 + 31498547 = 31498698
157 + 31498541 = 31498698
181 + 31498517 = 31498698

Showing the first eight; more decompositions exist.
