Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449226, here are decompositions:

47 + 31449179 = 31449226
173 + 31449053 = 31449226
197 + 31449029 = 31449226
239 + 31448987 = 31449226
317 + 31448909 = 31449226
509 + 31448717 = 31449226
587 + 31448639 = 31449226
647 + 31448579 = 31449226

Showing the first eight; more decompositions exist.
