Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448132, here are decompositions:

61 + 31448071 = 31448132
109 + 31448023 = 31448132
181 + 31447951 = 31448132
229 + 31447903 = 31448132
349 + 31447783 = 31448132
691 + 31447441 = 31448132
739 + 31447393 = 31448132
769 + 31447363 = 31448132

Showing the first eight; more decompositions exist.
