Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529054, here are decompositions:

61 + 31528993 = 31529054
211 + 31528843 = 31529054
223 + 31528831 = 31529054
241 + 31528813 = 31529054
313 + 31528741 = 31529054
331 + 31528723 = 31529054
421 + 31528633 = 31529054
433 + 31528621 = 31529054

Showing the first eight; more decompositions exist.
