Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498274, here are decompositions:

61 + 31498213 = 31498274
151 + 31498123 = 31498274
163 + 31498111 = 31498274
271 + 31498003 = 31498274
277 + 31497997 = 31498274
523 + 31497751 = 31498274
547 + 31497727 = 31498274
601 + 31497673 = 31498274

Showing the first eight; more decompositions exist.
