Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472684, here are decompositions:

73 + 31472611 = 31472684
97 + 31472587 = 31472684
541 + 31472143 = 31472684
577 + 31472107 = 31472684
631 + 31472053 = 31472684
643 + 31472041 = 31472684
673 + 31472011 = 31472684
751 + 31471933 = 31472684

Showing the first eight; more decompositions exist.
