Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524002, here are decompositions:

61 + 31523941 = 31524002
151 + 31523851 = 31524002
163 + 31523839 = 31524002
199 + 31523803 = 31524002
241 + 31523761 = 31524002
463 + 31523539 = 31524002
541 + 31523461 = 31524002
673 + 31523329 = 31524002

Showing the first eight; more decompositions exist.
