Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488692, here are decompositions:

61 + 31488631 = 31488692
73 + 31488619 = 31488692
199 + 31488493 = 31488692
211 + 31488481 = 31488692
223 + 31488469 = 31488692
229 + 31488463 = 31488692
421 + 31488271 = 31488692
601 + 31488091 = 31488692

Showing the first eight; more decompositions exist.
