Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529132, here are decompositions:

43 + 31529089 = 31529132
79 + 31529053 = 31529132
139 + 31528993 = 31529132
163 + 31528969 = 31529132
223 + 31528909 = 31529132
331 + 31528801 = 31529132
409 + 31528723 = 31529132
463 + 31528669 = 31529132

Showing the first eight; more decompositions exist.
