Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498952, here are decompositions:

3 + 31498949 = 31498952
73 + 31498879 = 31498952
103 + 31498849 = 31498952
139 + 31498813 = 31498952
211 + 31498741 = 31498952
313 + 31498639 = 31498952
439 + 31498513 = 31498952
673 + 31498279 = 31498952

Showing the first eight; more decompositions exist.
