Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498552, here are decompositions:

3 + 31498549 = 31498552
5 + 31498547 = 31498552
11 + 31498541 = 31498552
23 + 31498529 = 31498552
53 + 31498499 = 31498552
83 + 31498469 = 31498552
89 + 31498463 = 31498552
131 + 31498421 = 31498552

Showing the first eight; more decompositions exist.
