Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483658, here are decompositions:

61 + 31483597 = 31483658
109 + 31483549 = 31483658
211 + 31483447 = 31483658
229 + 31483429 = 31483658
307 + 31483351 = 31483658
331 + 31483327 = 31483658
397 + 31483261 = 31483658
421 + 31483237 = 31483658

Showing the first eight; more decompositions exist.
