Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612444, here are decompositions:

53 + 31612391 = 31612444
131 + 31612313 = 31612444
137 + 31612307 = 31612444
167 + 31612277 = 31612444
293 + 31612151 = 31612444
401 + 31612043 = 31612444
431 + 31612013 = 31612444
503 + 31611941 = 31612444

Showing the first eight; more decompositions exist.
