Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489226, here are decompositions:

79 + 31489147 = 31489226
157 + 31489069 = 31489226
163 + 31489063 = 31489226
199 + 31489027 = 31489226
367 + 31488859 = 31489226
607 + 31488619 = 31489226
733 + 31488493 = 31489226
757 + 31488469 = 31489226

Showing the first eight; more decompositions exist.
