Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498692, here are decompositions:

53 + 31498639 = 31498692
101 + 31498591 = 31498692
151 + 31498541 = 31498692
163 + 31498529 = 31498692
179 + 31498513 = 31498692
193 + 31498499 = 31498692
223 + 31498469 = 31498692
229 + 31498463 = 31498692

Showing the first eight; more decompositions exist.
