Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498700, here are decompositions:

43 + 31498657 = 31498700
61 + 31498639 = 31498700
109 + 31498591 = 31498700
151 + 31498549 = 31498700
229 + 31498471 = 31498700
421 + 31498279 = 31498700
487 + 31498213 = 31498700
577 + 31498123 = 31498700

Showing the first eight; more decompositions exist.
