Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592144, here are decompositions:

97 + 31592047 = 31592144
151 + 31591993 = 31592144
271 + 31591873 = 31592144
277 + 31591867 = 31592144
307 + 31591837 = 31592144
421 + 31591723 = 31592144
433 + 31591711 = 31592144
457 + 31591687 = 31592144

Showing the first eight; more decompositions exist.
