Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482692, here are decompositions:

61 + 31482631 = 31482692
79 + 31482613 = 31482692
181 + 31482511 = 31482692
193 + 31482499 = 31482692
349 + 31482343 = 31482692
421 + 31482271 = 31482692
463 + 31482229 = 31482692
523 + 31482169 = 31482692

Showing the first eight; more decompositions exist.
