Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622488, here are decompositions:

59 + 31622429 = 31622488
251 + 31622237 = 31622488
281 + 31622207 = 31622488
347 + 31622141 = 31622488
509 + 31621979 = 31622488
587 + 31621901 = 31622488
641 + 31621847 = 31622488
809 + 31621679 = 31622488

Showing the first eight; more decompositions exist.
