Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622830, here are decompositions:

53 + 31622777 = 31622830
89 + 31622741 = 31622830
101 + 31622729 = 31622830
131 + 31622699 = 31622830
137 + 31622693 = 31622830
167 + 31622663 = 31622830
251 + 31622579 = 31622830
293 + 31622537 = 31622830

Showing the first eight; more decompositions exist.
