Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541306, here are decompositions:

37 + 31541269 = 31541306
73 + 31541233 = 31541306
127 + 31541179 = 31541306
193 + 31541113 = 31541306
367 + 31540939 = 31541306
439 + 31540867 = 31541306
523 + 31540783 = 31541306
607 + 31540699 = 31541306

Showing the first eight; more decompositions exist.
